A coil component has a magnetic element body made of resin containing magnetic particles, a coil part embedded in the magnetic element body, conductor posts which are embedded in the magnetic element body and whose one ends are connected to the coil part and the other ends are exposed from the magnetic element body, an insulating layer interposed between the conductor posts and the magnetic element body, and other insulating layers interposed between the coil part and the magnetic element body. Since the insulating layer is interposed between the conductor posts and the magnetic element body, it is possible to ensure insulation performance between the conductor posts and the magnetic element body and to prevent the occurrence of peeling therebetween.

Coil component and manufacturing method therefor

To improve magnetic characteristics of a coil component having a structure in which an interlayer insulating film is provided between a spiral coil pattern and a magnetic element body. A coil componentincludes: an interlayer insulating filmcovering coil patterns CPto CPfrom one side in the axial direction of the coil patterns; a magnetic element body Mfilled in the inner diameter areas of the coil patterns CPto CP; and a magnetic element body Mcovering the coil patterns CPto CPfrom the one side in the axial direction through the interlayer insulating film. The interlayer insulating filmhas a protruding partA radially protruding to the inner diameter area, and the protruding partA is curved to the other side in the axial direction. Since the protruding partA is curved in the axial direction, the entrance of a magnetic path passing through the inner diameter area is made wider than when the protruding partA linearly protrudes to the inner diameter area. This suppresses deterioration in magnetic characteristics due to the presence of the protruding partA.

A coil component is provided with a coil part in which a plurality of conductor layers and a plurality of interlayer insulating layers are alternately laminated; and a sealing resin layer that covers the coil part. The conductor layers each include a spiral pattern. The interlayer insulating layers each cover an upper surface and a side surface of the spiral pattern. The recessed part is formed in the side wall surface of the interlayer insulating layer. A part of the sealing resin layer is embedded in the recessed part.

A method includes performing notification processing to, in a case where a communication between a communication apparatus and an information processing apparatus via an external apparatus is to be inexecutable, notify a user of at least one of a communication error as the cause of failure to perform communication between the communication apparatus and the information processing apparatus via the external apparatus, and or a method for solving the communication error.

Information processing apparatus performing notification about communication error causing communication via external apparatus to be inexecutable, control method, and storage medium for the same

First device information, which is information independent from settings of a device or functions of a device, is obtained from a device in bulk; second device information, which is information that depends on settings of a device or functions of a device, is obtained; and the obtained first and second device information are stored in a storage unit. A device connected through communication is then specified on the basis of the obtained first device information.

Information processing apparatus, information processing method, and computer-readable medium

A control method for controlling an information processing apparatus communicating with a communication apparatus capable of performing at least wireless communication using a first frequency band and wireless communication using a second frequency band includes transmitting connection information and frequency band information to the communication apparatus upon receipt of an execution instruction, where the connection information is used to wirelessly connect to the external apparatus and the frequency band information is related to a frequency band used to wirelessly connect to the external apparatus.

Information processing apparatus and control method

Disclosed herein is a coil component that includes: a coil part in which a plurality of conductor layers and a plurality of interlayer insulting layers are alternately laminated, the coil part having a mounting surface substantially parallel to the lamination direction and an upper surface substantially parallel to the lamination direction and positioned on an opposite side to the mounting surface; and a direction mark comprising a conductive material that covers a part of the conductor layers exposed on the upper surface.
