ABSTRACT:
A planar magnetic device in which the high-frequency loss in the coil conductor can be reduced. The device comprises a planar coil formed of a coil conductor constituted by a plurality of conductor lines. The coil conductor is provided in the form of a spiral. The planar coil is interposed between two insulating layers which are sandwiched between two soft-magnetic layers.
