Abstract
An inductor includes a wire including a conducting line, and an insulating film disposed on an entire circumferential surface of the conducting line, and a magnetic layer embedding the wire. The magnetic layer contains a magnetic particle. The magnetic layer includes a first layer in contact with the circumferential surface of the wire, a second layer in contact with the surface of the first layer, . . . and the n-th layer (n is a positive number of 3 or more) in contact with the surface of the (n−1)th layer. In the two layers adjacent to each other in the magnetic layer, the relative magnetic permeability of the layer closer to the wire is lower than the relative magnetic permeability of the layer farther from the wire.
