Abstract

A laminated inductor element is configured to prevent warpage of the entire element with a structure in which a non-magnetic ferrite layer on an upper surface side is reduced in thickness to achieve a reduction in height of the entire element, a non-magnetic ferrite layer on a lower surface side is increased in thickness to be thicker than the non-magnetic ferrite layer so as to prevent a metal component diffused from a magnetic ferrite layer from coming into electrical contact with a land electrode of a mounting substrate, and an inductor is disposed toward the lower surface side across a non-magnetic ferrite layer.
