Abstract
An inductor of the present invention includes a plurality of insulating layers being stacked and coil patterns respectively provided on predetermined layers of the insulating layers. The coil patterns are provided on at least two of the insulating layers, and electrically connected to each other. With this arrangement, it is possible to improve Q of the inductor without increasing the size of the inductor.
