<p>Disclosed is a reactor having a reduced number of components and having a lower manufacturing cost; also disclosed is a reactor manufacturing method. The disclosed reactor has a cylindrical molded coil formed by covering a coil with a resin, wherein the molded coil is sealed by an iron powder mixed resin to which iron powder has been admixed. The reactor has an axial core unit, and single or multiple ring-shaped core members. The ring-shaped core members are disposed outside the outer surface of the axial core unit such that the axial core unit is inserted inside the inner surface of said ring-shaped core members, and the molded coil is disposed outside the outer surface of the ring-shaped core member such that the ring-shaped core members are inserted inside the inner surface of said molded coil. A protrusion protruding inwards from the inner surface of the molded coil contacts the axial end surface of a ring-shaped core member.</p> |
