PROBLEM TO BE SOLVED: To provide a method for manufacturing a resin molded product, wherein an opening part is provided to a resin molded object at a predetermined region, constituted so that the opening part is formed immediately before or on the way of the molding of the resin molded object to abolish post-processing perforation and the peripheral edge of the opening part is made thick to enhance the strength or rigidity of the opening part. SOLUTION: In molding the sheetlike resin 10a supplied to the mold surface 22 of a mold 20 into the resin molded object 11 having a shape corresponding to the mold surface 22, the region 16 corresponding to the opening part 15 of the sheetlike resin 10a on the mold surface 22 is pressed by a pressure fixture 23. The fixture 23 has an annular recessed part 23b1 corresponding to the peripheral edge 15a of the opening part 15, before molding or on the way of molding, during a period when the sheetlike resin 10a is held to a plastically deformable state, to form the opening part 15.
