摘要： An inductor includes a wire having a width W, and a first electrode and a second electrode continuous to each of both ends of the wire. The wire, the first electrode, and the second electrode are present on the same plane. The plane area S1 of the first electrode and the plane area S2 of the second electrode are a square value (W2) or more of the width W. An area in which the wire is disposed is positioned between the first electrode and the second electrode. The area has a length X in a longitudinal direction equal to a length L between the first electrode and the second electrode along a facing direction of the first electrode and the second electrode, and a length Y in a short-length direction in a direction perpendicular to the longitudinal direction. The length X in the longitudinal direction is 1.5 times or more of the length Y in the short-length direction.

摘要： 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.
