The coil conductor disposed inside a component body extends substantially helically by alternately connecting a plurality of circulating conductive layers and a plurality of via hole conductors. The circulating conductive layers each extend so as to form a part of a substantially quadrangular track having a relatively short side and a relatively long side along an interface between the insulating layers. The via hole conductors each penetrate the insulating layer in a thickness direction. The line width of a short side portion of the circulating conductive layer is wider than that of a long side portion of the circulating conductive layer.

Abstract: An inductor includes a first air-bridge section and a second air-bridge section. The first air-bridge unit extends in a floating location over a substrate between a plurality of support locations on the substrate. The second air-bridge unit extends in a floating location over the first air-bridge unit between a plurality of support locations on the first air-bridge unit. This arrangement enables the first and second air-bridge sections to be connected in parallel, thus branching a flowing current. Thus, the conductor loss in each of the first and second air-bridge sections is reduced.
