Abstract
An inductor includes a first conductor, a second conductor, an insulation film, and a magnetic body. The first conductor spirally extends in a plane. The second conductor spirally extends in a plane. The second conductor is stacked on and joined to the first conductor. The insulation film covers a surface of the first conductor and a surface of the second conductor. The magnetic body covers a surface of the insulation film and embeds the first conductor and the second conductor. The first conductor and the second conductor are connected to form a helical coil.
