Abstract:
A method of manufacturing an inductor having a conductor coil embedded in a magnetic chip containing a magnetic material, with an external terminal electrode electrically connected to the conductor coil on the outer surface of the magnetic chip, the method comprising the steps of:holding the conductor coil in a cavity of a mold for injection molding by fitting the conductor coil to a coil supporting member provided in the cavity such that the coil supporting member contacts substantially the entire length of the conductor coil;performing a primary injection molding by injecting a molten magnetic chip molding material into the cavity;performing a secondary injection molding by removing the coil supporting member from the cavity and injecting a molten magnetic chip molding material into a space in the cavity which was occupied by the coil supporting member so as to define a molded product having the conductor coil embedded therein;removing the molded product having the conductor coil embedded therein from the mold; andcutting the molded product so as to expose end parts of the embedded conductor coil.
