Abstract

An inductor includes a stacked body having a first through hole, and an insulation film covering the stacked body. The stacked body includes a first wiring, a first insulation layer stacked on the first wiring and including a second through hole exposing the first wiring, a first adhesive layer stacked on the first insulation layer and including a third through hole communicating with the second through hole, a second wiring stacked on the first adhesive layer and including a fourth through hole communicating with the third through hole, a second insulation layer stacked on the second wiring and including a fifth through hole communicating with the fourth through hole, and a first through electrode with which the second to fifth through holes are filled. The first and second wirings are connected to form a helical coil. The fifth through hole has a larger planar shape than the fourth through hole.
