Abstract: An inductor component includes an inductor electrode having two metal pins that form input and output terminals and a connecting conductor that connects one end of each of the metal pins to each other, the inductor electrode arranged such that other ends of the metal pins oppose each other, and a resin layer containing the inductor electrode such that other ends of the metal pins are exposed. The resin layer is formed having a single-layer structure. Variation in the characteristics of the inductor electrode can be reduced as compared to a case where the parts corresponding to the metal pins of the inductor electrode are formed as via conductors or through-hole conductors. Because the resin layer has a single-layer structure, stress acting on joint portions between the metal pins and the connecting conductor can be reduced, which makes it possible to improve the reliability of the inductor component.

Abstract: A first resin layer (resin insulating layer) is formed by forming first and third covering portions in close contact with peripheral surfaces of respective end portions of first and second metal pins on the side closer to first end surfaces thereof, and by forming a body portion in a state of covering the respective surfaces of the first and third covering portions. Therefore, even when the first resin layer is thermally contracted, boundary regions of the one principal surface of the first resin layer around the respective end portions of the first and second metal pins on the side closer to the first end surfaces are filled with the first and third covering portions. Hence gaps can be prevented from being generated in those boundary regions, and a columnar conductor (first metal pin) can be avoided from deviating in position.

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.

Abstract: A module includes an insulating layer, a ring-shaped magnetic core built in the insulating layer, a coil electrode disposed in the insulating layer so as to spirally wind around the magnetic core, and heat-dissipating metal bodies respectively disposed outside and inside the magnetic core within the insulating layer. Building the magnetic core into the insulating layer as described above eliminates the need to provide the principal face of the insulating layer with a large mounting area for mounting a coil formed by the magnetic core and the coil electrode. This allows the area of the principal face of the insulating layer to be reduced to achieve miniaturization of the module. The presence of the heat-dissipating metal bodies respectively disposed outside and inside the magnetic core within the insulating layer improves dissipation of the heat generated from the coil.
