Abstract: A coil component includes an exterior body, a coil positioned inside the exterior body, and terminal electrodes arranged on a surface of the exterior body and connected to lead parts of the coil. The exterior body is a columnar shape or a polyhedron shape, and includes a first plane for arranging the terminal electrodes, a second plane opposing the first plane, and one or more connecting planes connecting the first plane and the second plane; and the exterior body has a jagged edge on at least part of an edge positioned between the second plane and the one or more connecting planes.

Abstract: An attachment structure of a flat wire harness includes: an attachment target member; a flat wire harness; and an attachment part. In the flat wire harness, a through hole is formed in a part of a base material where a plurality of electrical wires are not disposed. The attachment part includes a rod-like part passing through the through hole, a fixing part provided to a first end portion of the rod-like part to fix the rod-like part to the attachment target member, and a retaining part provided to a second end portion of the rod-like part to prevent the rod-like part from coming out of the through hole. An outer size of the retaining part is larger than a dimension of the through hole, and the dimension of the through hole is equal to or larger than a thickness of the rod-like part.

Abstract: The present disclosure relates to an attachment structure for attaching a wiring member to an instrument panel reinforcement, which is an attachment object, provided near an instrument panel. The wiring member includes a linear transmission member that transmits electricity or light, and a covering member that covers the linear transmission member. The wiring member attachment structure includes a rail member provided on the instrument panel reinforcement, and an insertion member that is provided on the covering member and inserted into the rail member. The wiring member is attached to the instrument panel reinforcement in a state in which the insertion member is inserted into the rail member.

Abstract: A coil device 1 comprises a coil 10, a T-shaped core 20 including a columnar portion 21 around which the coil 10 is disposed and a flange 22 formed at a first end 21a of the columnar portion 21 in an axial direction thereof, and an exterior body 30 covering the coil 10 and the columnar portion 21 and made of an exterior material including magnetic particles and a resin. The core 20 is provided with a recess 40 including at least one of a first recess 41 or a second recess 42. The first recess 41 extends between the first end 21a and a second end 21b of the columnar portion 21 in the axial direction. The second recess 42 extends from an inner side towards an outer side of the flange 22.

Abstract: An injection molding composition, having a small fluctuation characteristic and a better characteristic, is provided. The above composition is the injection molding composition comprising a ferrite powder which is a collection of ferrite particles, a first binder and a second binder. A weight and a specific surface area of the ferrite powders are represented by Wp and S, and a weight and a density of the first binder and the second binder is represented by Wb1, Wb2, and Db1, Db2. A hypothetical thickness Tb1 of the first binder is 2.0 to 15.0, and a hypothetical thickness Tb2 of the second binder is 16.5 to 32.0. In the composition, it is preferable that coated ferrite particles coating the outer circumference of the ferrite particles with the first binder and the second binder exist.
