PROBLEM TO BE SOLVED: To provide a manufacturing method of a resin molded product wherein it does not take a long time for the solidification of the molded product and the productivity is not deteriorated while improving the hydrolysis resistance of a polyester-based bioplastic by mixing an nonhydrolytic agent into a base resin of the polyester-based bioplastic. SOLUTION: In the method of manufacturing the resin molded product 50 mixed with the nonhydrolytic agent of suppressing the hydrolysis of a base resin molecule by being combined with the base resin molecule, the inclusion of the nonhydrolytic agent is prepared beforehand so that the nonhydrolytic agent is diffused with time, and the inclusion is mixed into base resin to perform molding and, as the result, combination between the base resin molecule and the nonhydrolytic agent is suppressed upon molding, and the suppression of the combination is released after the molding.
