CD4 mimic compounds having improved efficacy for anti-HIV treatment and more improved pharmacokinetics are provided. The compounds are represented by formula (I): wherein Ris CH(OCH)—OCHor CH; Ris O or NH; n is 3 to 25; and m is 4 to 22, or a salt thereof. HIV infection inhibitor compositions including the compound or a salt thereof as an active ingredient are also disclosed.

In a coil component, fixing strength of an external terminal is improved. In the coil component, on the end face of the element body, the center position of the external terminal electrode in the first direction is biased toward the center position of the end face with respect to the center position of the outer end portion. Therefore, the fixing area between the external terminal electrode and the element body is increased on the center position side of the end face, and thus fixing strength between the external terminal electrode and the element body is improved.

Coil component

An electronic component preventing peeling of an external terminal is provided. Since each of the external terminal electrodes on the upper face has a U-shaped outline, stress concentration is less likely to occur at an inner end portion than in the external terminal electrode having a corner at the inner end portion. Therefore, for example, even when an impact is applied, a situation in which the external terminal electrode peels off from the upper face due to stress concentration is prevented.

Electronic component

In a coil component, a non-magnetic part is bridged between a first coil and a second coil in a cross section of an element body. Therefore, a magnetic flux in a direction along a magnetic core of the first coil and a magnetic core of the second coil is hindered by the non-magnetic part between the first coil and the second coil. Accordingly, a magnetic flux of the first coil and a magnetic flux of the second coil are difficult to interfere with each other.

In the coil component, external stress applied when the upper coil structure, the lower coil structure, and the magnetic sheet are stacked is dispersed by the undulation of both main surfaces of the magnetic sheet. By dispersing the stress in this manner, a situation in which defects such as cracks occur in the coil structure is effectively suppressed.

By overlapping the protruding portion of the first insulator and the protruding portion of the second insulator via the protruding portion of the substrate, the DC superposition characteristic of the coil component is improved.

In an insulation layer of a coil component, a thickness of a second covering part and a third covering part located on the penetration hole side of a first covering part is thinner than that of the first covering part. A stray capacitance occurring between a flat coil pattern and external terminal electrodes is reduced by making the first covering part of the insulation layer thicker than the second covering part and the third covering part. Further, since the second covering part and the third covering part of the insulation layers are thinner than the first covering part, a magnetic volume is increased while external dimensions of the base body is maintained, and thus a high inductance is realized.

In a coil component, a main body portion is made of a metal magnetic powder-containing resin, and thus a resin component appears on end surfaces of the main body portion. In addition, since external terminal electrodes are made of a conductive resin, a resin component also appears on the surfaces of the external terminal electrodes. Accordingly, insulating coating layers are integrally covered with high adhesion with the end surfaces of the main body portion and the external terminal electrodes by the insulating coating layers coming into contact with the end surfaces of the main body portion so as to straddle the external terminal electrodes.

In a coil component, a first planar coil and a second planar coil are wound around a common magnetic core and are magnetically coupled to each other. However, the first planar coil and the second planar coil are not electrically connected to each other and form coil structures which are separate from each other. Thus, as compared with a case in which the first planar coil and the second planar coil form one coil structure, the first planar coil and the second planar coil are less likely to affect each other's characteristics.

In an electronic component, a terminal electrode has a thickest portion and a part thinner than the thickest portion. Accordingly, an increase in solder fillet forming region occurs when the electronic component is solder-mounted onto a predetermined mounting substrate. In the electronic component, mounting strength is improved as a result of the increase in solder fillet forming region. In addition, in the electronic component, the thickest portion overlaps a bump electrode in a direction orthogonal to the lower surface of an element body. Accordingly, the impact that is applied to the electronic component during the mounting onto the mounting substrate is reduced and the impact resistance of the electronic component is improved.

Electronic component and coil component

In a coil component, a double coil is configured of a first coil portion and a second coil portion, and a first through conductor of the first coil portion and a second through conductor of the second coil portion are adjacent to each other. Thus, the first coil portion and the second coil portion have enhanced magnetic coupling at locations (that is, the first through conductor and the second through conductor) at which planar coil patterns of upper and lower surfaces of an insulating substrate are connected, in addition to magnetic coupling in the planar coil patterns wound around a through hole. Therefore, according to the coil component, a high coupling coefficient between the first coil portion and the second coil portion is realized.

A touch panel includes first arrays of electrodes, second arrays of electrodes, and an output part where leads extending from triangular end electrodes of the first arrays and the second arrays are connected to an external device. At least one corner electrode of the end electrodes which is located in a corner on one of four sides of the detection part where the output part is located has an area that is less than an area of other end electrodes.
