Abstract

An inductor includes a wire, and a magnetic layer covering the wire. The wire includes a conducting line, and an insulating layer covering the conducting line. The magnetic layer includes a magnetic particle and a binder. In a peripheral region of the wire, a filling rate of the magnetic particle is 40% by volume or more. The peripheral region is a region of the magnetic layer traveling outwardly from an outer peripheral surface of the wire by 1.5 times an average of the longest length and the shortest length from the center of gravity C of the wire to an outer surface of the wire in a cross-sectional view.
