Abstract
Substrate-side wiring electrode patterns 16, which form a part of a coil electrode 12, are provided on a wiring substrate 20, and as a result reductions in the size and profile of a resin insulating layer 31, in which a coil core 11 is buried, can be achieved. Therefore, reductions in the size and the profile of a coil module 1 can be achieved compared with a coil module of the related art which is formed by mounting a coil component on a wiring substrate. In addition, since the substrate-side wiring electrode patterns 16, which form a part of the coil electrode 12, are provided on the wiring substrate 20, the heat generated by a coil 10 can be efficiently released from the substrate-side wiring electrode patterns 16 to the wiring substrate 20. Therefore, the heat dissipation property of the coil module 1 can be improved at low cost.
