PROBLEM TO BE SOLVED: To cause neither deformation nor distortion to a primary molding part due to injection pressure or the like in molding a secondary molding part. SOLUTION: A method of manufacturing a two-color molding 28 includes molding an optical element part 1 in primary molding, then molding a colored outer peripheral part 2 in secondary molding, and at the same time, integrating the optical element part 1 with the colored outer peripheral part 2. A thin-walled part 1b for absorbing stress applied to the optical element part 1 is formed at the optical element part 1 in secondary molding. COPYRIGHT: (C)2010,JPO&INPIT |
