PROBLEM TO BE SOLVED: To provide a resin molded article which can prevent deterioration caused by light and can be used over a long period without losing an irregular pattern, even when worn, to provide an apparatus for producing the same, and to provide a method for producing the same. SOLUTION: This resin molded article having an irregular pattern is characterized by melting a mixture of resin pellets (the first resin material) with a master batch (the second resin material) until semi-melting one of the resin materials, molding the semi-melted mixture into a resin molded article having a prescribed shape, and then coating the surface of the molded article with a transparent coating 34 (transparent member) containing an ultraviolet ray absorbent. Since the resin pellets and the master batch have different colors, flowing properties and melting points, respectively, the mixture gives the irregular pattern, after melted. Since not reacting with oxygen, the resin molded article P coated with the transparent coating 34 can prevent deterioration caused by light and can be used over a long period. Since having the irregular pattern not only on the surface but also in the inner portion, the resin molded article P does not lose the irregular pattern, even when worn.
