PROBLEM TO BE SOLVED: To mold a large-sized uncoated resin part good in appearance. SOLUTION: A film layer 10 formed by laminating a transparent resin and a colored resin is set to the upper mold 52 of an injection molding apparatus 51 and, after the upper mold 52 and a lower mold 53 are closed, a base material resin 11a becoming a base material layer 11 is injected in the space S between the film layer 10 set to the upper mold 52 and the lower mold 53 to mold a front fender 1. At this time, the base material resin 11a is charged in the space S from a position where the base material resin 11a can be allowed to arrive every nook and corner of the space S between the film layer 10 and the lower mold 53 only by one flow F expanding in an almost concentric circular form.
