The present disclosure provides an inductive element capable of lowering a Q-value. An inductive element includes a first cover and a second cover covering an annular core, and a first winding and a second winding wound around a region of the core, the first cover and the second cover. The first cover covers a part of an inner circumferential surface of the core, a part of an outer circumferential surface and an end surface on one end side in an axial direction. The second cover covers a part of the inner circumferential surface of the core, a part of the outer circumferential surface an end surface on the other end side in the axial direction.

An electromagnetic interference suppressor is disposed so as to be effective for noise in a wide frequency band including a high frequency band. Provided is an electronic device including an electromagnetic interference suppressor; an interfering object configured to generate an electromagnetic wave; an interfered object to be affected by the electromagnetic wave; a substrate configured to mount thereon the interfering object and the interfered object; and the electromagnetic interference suppressor disposed in parallel to the substrate, and is disposed along only one of the interfering object and the interfered object. When an end portion of the interfering object opposed to the interfered object is defined as a first end portion, and an end portion of the interfered object opposed to the interfering object is defined as a second end portion, one end portion of the electromagnetic interference suppressor is disposed between the first end portion and the second end portion.

Electronic device and method for disposing electromagnetic interference suppressor

A device is provided with a potential noise radiating source capable of radiating potential noise, a potential noise receiving portion capable of receiving the potential noise and an electromagnetic interference suppression body. The electromagnetic interference suppression body is made by binding flaky soft magnetic metal powder with a binding component and has a sheet-like shape. The electromagnetic interference suppression body is formed with a plurality of slits. The electromagnetic interference suppression body is provided to straddle the potential noise radiating source and the potential noise receiving portion.

Device provided with electromagnetic interference suppression body

An antenna device, which has wide-angle directivity and a configuration suitable to be used in a portable electronic apparatus, includes a flat board-like substantially rectangular soft magnetic body, and a loop-shaped coil disposed from a front surface to a rear surface of the soft magnetic body such that a region surrounded by the coil includes at least a part of a specific edge, i.e., one edge out of four edges of the soft magnetic body, and does not include a facing edge that faces the specific edge.
