PROBLEM TO BE SOLVED: To provide a manufacturing method of a resin molded article capable of more uniformizing the mutual mixed state of resins by the combination of the specific resins and a plasticizer. SOLUTION: After a composition comprising a first resin becoming a main component, the second resin mixed with it and the plasticizer capable of swelling at least the second resin is kneaded under heating, the kneaded composition is extruded into a predetermined cross-sectional shape to obtain an extrusion molded article. In this manufacturing method of the resin molded article, the prescribed swelling time of the second resin calculated on the basis of pulse NMR when the second resin is swollen at 30°C using the plasticizer is set to 25 min or below.
