Abstract
A reactor that is fabricated with high productivity is provided. The reactorincludes an annular magnetic core, a coil molded productA, and an external resin portion. The coil molded productA is disposed around an outer periphery of the magnetic core, the external resin portioncovers an outer periphery of an assemblyof the magnetic coreand the coil molded productA. The magnetic coreincludes a plurality of core pieces that are combined so as to form an annular shape. The magnetic coreis fixed in the annular shape using the external resin portionthat covers the magnetic core without use of adhesive. The coil molded productA includes a coilformed of a helically wound wireand an internal resin portionthat maintains the coilin a compressed state. Since the magnetic coreis formed without adhesive, a bonding step is not required. Due to use of the coil molded productA, the coilneeds not be compressed while forming the reactor. Thus, the reactoris fabricated with high productivity.
