Abstract

An inductor includes an annular core, and a first coil and a second coil which are wound around the core. The core has an internal surface, an external surface, a first end surface, and a second end surface. The first coil and the second coil include a first coil piece having a length of one turn and a second coil piece having a length of one turn. The first coil piece and the second coil piece surround the internal surface, the first end surface, the external surface, and the second end surface of the core. The first coil piece has, at its tip, a joint portion to be joined to the second coil piece, and the second coil piece has, at its tip, a joint surface to be in contact with the joint portion. Thus, the resistance value of the coil is reduced.
