COIL COMPONENT, COIL DEVICE, AND METHOD FOR PRODUCING COIL COMPONENT

WIPO Patent Application WO/2023/144913

A1

[Problem] To provide: a coil component, in which the axial direction length including a gap and a coupling part of two coil elements is shortened for size reduction, and deterioration in characteristics and the risk of heat generation that could occur when the leakage magnetic flux comes into contact with a twisted portion can be reduced; a coil device; and a method for producing the coil component. [Solution] The present invention comprises: a first coil element 111 and a second coil element 112 that are formed from a coil winding body which is obtained by rectangularly stacking one rectangular wire 101 in an edge-wise manner, which is divided into two at a predetermined position and folded back, and in which the opposing side surfaces of the coil winding body are disposed so as to be parallel and in close contact with each other; and a coupling part 113 that couples the coil elements 111 and 112. The coupling part 113 is provided along upper surfaces of the coil elements 111, 112 so as to straddle the two coil elements 111, 112. The coupling part 113 includes, at one portion thereof, a twisted section 123D where the rectangular wire 101 is twisted 180°.
