Inductor

Abstract

Provided is an inductor 1 comprising a frame-shaped core 2 and one bus bar 3. The core 2 has a first core 2A having a first columnar portion 13A, and a second core 2B having a second columnar portion 13B arranged in parallel to the first columnar portion 13A. The bus bar 3 is wound around the first columnar portion 13A and the second columnar portion 13B in a flatwise winding. If one side in the longitudinal direction of each columnar portion is defined as a front side and the other side thereof is defined as a rear side, the bus bar 3 includes: a first winding part 3A spirally wound around the first columnar portion 13A from the front side toward the rear side; a second winding part 3B spirally wound around the second columnar portion 13B from the rear side toward the front side in the same winding direction as the winding direction of the first winding part 3A; and a connection part 15 connecting a rear end of the first winding part 3A and a rear end of the second winding part 3B.
