PROBLEM TO BE SOLVED: To provide an injection molded article whose surface is free of scorching and color irregularities and at the same time to avert the waste of resources. SOLUTION: A manufacturing method of a resin molding is provided, of which molding is molded with the lamination of an outer layer resin material and an inner layer resin material and of which method comprises the step of supplying the outer layer resin material wherein the outer layer resin material is supplied into a mold through the outer layer resin material supplying passage 1 of the injection molding apparatus M and the step of supplying the inner layer resin material wherein the inner layer resin material is supplied into the mold through the inner layer resin material supplying passage 2 of the injection molding apparatus. The method has the transferring step wherein, before the injection molding step as to the lamination-molded resin molding, the outer layer resin material remaining in the outer layer resin material supplying passage 1 is transferred to the inner layer resin material supplying passage 2.
