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 coil component is provided with only first and second columnar conductors that are a part of a coil electrode. This can simplify the manufacturing process and reduce the cost of the coil component. A wiring substrate is provided with substrate-side wiring electrode traces that form the remaining part of the coil electrode. In the process of forming the wiring substrate using a substrate forming technique commonly used, the substrate-side wiring electrode traces can be easily formed together with other wiring electrodes. Therefore, when the coil electrode is configured to be formed by placing the coil component on the wiring substrate, a coil module including the coil component can be inexpensively manufactured.

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.
