Abstract
A semiconductor device includes at least one semiconductor element having a switching function; a conductive member that forms a path of a current switched by the semiconductor element, and that is made of a first material; and a covering layer that covers at least a portion of the conductive member, and that is made of a second material. The second material satisfies at least one of the following three requirements: (a) having a magnetic permeability higher than the first material; (b) having an electrical resistivity higher than the first material; and (c) having a dielectric loss tangent larger than zero.
