PROBLEM TO BE SOLVED: To provide a method for sticking a protective film smoothly on the surface of a reflector in the accurate position at the same time as molding of the reflector. SOLUTION: A protection film 4 is fitted to the inside of the die for molding the reflector and thumbtacks 3 are provided on the moving side or the stationary side of the die for molding the reflector. While pressing the protective film 4 by the thumbtacks 3, injection molding is performed by feeding a resin molding the reflector into the die. Thereby, both a float of the protective film and a deviation in a position due to the pressure, in which the resin is introduced at a time of injection molding, are prevented. Accordingly, the protective film is stuck smoothly on the accurate position of the surface of the reflector.
