An aluminum electrolytic capacitor includes: an exterior case of a bottomed cylindrical shape for accommodating a capacitor element in which an anode foil and a cathode foil are wound in an overlapping manner with a separator interposed therebetween; and an elastic sealing member for sealing an opening of the exterior case, wherein the exterior case is formed with, on an outer circumferential surface, a plurality of tapered concave portions whose depth in the radial direction becomes shallow from the bottomed cylindrical bottom toward the opening side, whereby a tapered raised portion, which is raised toward the center side in the radial direction, is formed on an inner circumferential surface located on the back surface of the concave portion, and the capacitor element is abutted and supported by the raised portion.

Electronic component

The present invention relates to a magnetic sensor with which magnetic characteristics are made extremely stable by consideration of an area of contact of a base layer of a magnetic substance and a semiconductor substrate. On a semiconductor substrate () a plurality of Hall elements () are embedded so as to be coplanar to a top surface of the semiconductor substrate while being mutually spaced apart by a predetermined distance, and above the Hall elements and the semiconductor substrate, a base layer (), having coefficient of thermal expansion differing from that of the Hall elements and partially covers a region of each Hall elements, is formed via a protective layer (), and a magnetic flux concentrator (), having an area larger than the base layer and with magnetic amplification, is formed on the base layer. An area of contact of the base layer of the magnetic substance and the semiconductor substrate is made small to lessen the generation of an offset voltage.

Magnetic sensor and method of manufacturing thereof

The present invention provides an optical device that is miniature, is highly sensitive and has a simplified package, and a manufacturing method thereof with high production efficiency and high reliability. The present invention is an optical device comprising: a photoelectric conversion element () having at least one photoelectric conversion portion () which is formed on a substrate (); a sealing material (); and a connection terminal (). The optical device comprises an optical window which is an interface between the photoelectric conversion element () and an outside of the optical device; and an aperture () formed in the sealing materialand whose bottom face is the optical window. An entire face of the optical window is exposed to the outside. An optical adjustment element () may be formed on the interface. In this case, the interface between the optical adjustment element () and the outside is the optical window.
