PROBLEM TO BE SOLVED: To provide a reactor in which a radiation fin is fixed more simply by using members that constitute the reactor.SOLUTION: The reactor includes: an annular circular magnetic core 200 having a pair of coil-wound parts 220; and a pair of coil elements 110a, 110b that are disposed on outer peripheries of both the coil-wound parts 220. The reactor further includes a radiation fin 300 and a resin part 120. In the resin part 120, the magnetic core 200, at least one of the coil elements 110a, 110b, and the radiation fin 300 are integrally molded. Since the radiation fin 300 is integrally molded by the resin part 120, at least one of the coil 110 and magnetic core 200 is protected by the resin part 120, and the radiation fin 300 is readily held to at least one of the coil 110 and magnetic core 200. |
