A laminated inductor, which offers high inductance while suppressing increase in direct-current resistance, has a rectangular solid laminate and a pair of terminal electrodes formed only on the bottom face of the laminate, wherein a folded conductor piece is provided on the first magnetic layer in a manner constituting around one turn worth of the windings, with one end placed near the first corner and the other end placed at a position toward the center and away from this one end so as not to overlap with the one end, while one of multiple sets of coil conductor pieces, each set constituting around one turn worth of the windings, is placed on multiple magnetic layers in the laminate.

Laminated inductor

A multilayer inductor includes a plurality of conductor layers for a coil, a plurality of magnetic substance layers, the magnetic substance layers and the conductor layers laminated alternately, and at least a magnetic flux restrictor layer disposed to block magnetic flux passing through the inner region of the coil. The magnetic flux restrictor layer is thinner at the center part of the coil than it is in a region near one of the conductor layers.
