ABSTRACT:
A printed circuit board (PCB) having a three-dimensional spiral inductor, which includes a plurality of insulating layers and conductor layers. The PCB comprises a plurality of coil conductor patterns made of conductive material and shaped into strips, which is provided on the plurality of conductor layers, respectively, such that the plurality of coil conductor patterns are parallel to each other and positioned on the same plane perpendicular to the conductor layers, and in which each of the plurality of coil conductor patterns is longer than an adjacent inner coil conductor pattern.
