PROBLEM TO BE SOLVED: To provide a molding method capable of manufacturing a resin molded body with a surface functional layer by injection molding.SOLUTION: The molding method for the resin molded body provided with the functional layer on the surface by injection molding includes: a step (step-1) in which a film 4 with a thickness of 0.1-2 mm, a melting point of 220°C or higher, a shrinkage at 200°C measured based on JISC2318 of 5-40%, and a functional layer on the surface, is arranged between one mold 1 and the other mold 3, and after the molds are clamped to form a molding cavity, a thermoplastic resin is injected into the cavity; and a step (step-2) in which the film is peeled off from the molded body. |
