PURPOSE:To facilitate positioning and molding operations, by a method wherein induction heating coil is molded of heat-resistant resin for a mold material integrally, and buried into a mold made of resin for molding. CONSTITUTION:A female and male molds 1, 2 are combined together and a cavity 5 which is filled with a resin powdery body or a molding material obtained by mixing a powdery body such as ceramics or a metal or a fiber or whisker with the resin powdery body is formed between the molds 1, 2. Induction heating coils 6, 7 are obtained by heating and pressure molding of heat-resistant resin 8, 9 integrally into cylindrical state and those coils 6, 7 are buried into the female and male molds 1, 2 respectively. A cylindrical heat- sensitive material 16 of high magnetic permeability such as ferrite is stuck to inner walls of the resin of which the induction heating coils 6, 7 have been molded integrally. The induction heating coils 6, 7 and electric wires 11, 12 which are connected with those coils are in a tubular state and cooling water is supplied from a water tank 13 by a pump 14 through a valve 15. With this construction, setting of a position of the induction heating coil 6 is performed easily.
