Abstract
A pre-molded part is formed by pre-molding an insert with a pre-molded member, and then the pre-molded part is inserted into an over-molded member composed of thermo plastic resin. After applying a heat treatment with a temperature lower than a crystalline melting point of the pre-molded part to the pre-molded part surrounding the insert, a firm contact between the insert and the resin surrounding the insert without a gap at the interface between those parts is obtained.
