The purpose of the present invention is to provide: a magnetic element for wireless power transmission, which is capable of feeding power with high power transmission efficiency, while increasing the heat dissipation performance; and a method for manufacturing the magnetic element for wireless power transmission magnetic element for wireless power transmission have configurations that respectively comprise planar coils through which an alternating current passes and magnetic parts which are arranged in parallel in the intervals between the copper wires of the planar coils when viewed in cross section. The magnetic parts comprise an epoxy resin in which iron-based amorphous particles FINEMET® serving as magnetic particles are dispersed, and the magnetic parts are integrated with the planar coils by being bonded to the planar coils in an electrically insulated state by means of the epoxy resin. |
