A method for coating a polypropylene resin molding is disclosed, comprising irradiating the surface of a molding of a polypropylene resin selected from a polypropylene and a propylene-ethylene block copolymer with an ultraviolet light having an irradiating wavelength in the region of 300 nm or less, coating the irradiated surface with a primer, and further coating the coated surface with a coating material. A method for coating a polypropylene resin molding is also disclosed, comprising coating the surface of a molding of a polypropylene resin selected from a polypropylene and a propylene-ethylene block copolymer with a primer, irradiating the coated surface with an ultraviolet light having an irradiating wavelength in the region of 300 nm or less, and further coating the irradiated surface with a coating material.
