PROBLEM TO BE SOLVED: To provide a manufacturing method of a resin product easy to form a film member having predetermined surface roughness to the surface of a resin body having every shape like a reflecting cup body in a close contact state without applying special processing to a mold itself. SOLUTION: When the reflecting cup body 21 having a predetermined shape is molded by injecting a thermally melted molding resin 18 in the space part of the mold 11 clamped by the cavity 12 of a female mold plate and the core 13 of a male mold plate, the thermoplastic film member 14 is arranged so as to be closely brought into contact with the surface of the core 13 and the molding resin 18 is injected in the space part formed by the film member 14 and the cavity 12 to form the reflecting cup body 21 wherein the surface of the resin body 18a is covered with the film member 14.
