PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin molded product, which has good appearance, by partially welding a functional member to a thermoplastic resin foamed sheet shaped into a predetermined shape without leaking a resin. SOLUTION: The manufacturing method of the thermoplastic resin molded product includes a process (1) for bringing the thermoplastic resin foamed sheet 1 preliminarily shaped into the predetermined shape into contact with a mold 3 which has a recessed part for welding the functional member formed thereto and can be sucked under vacuum, a process (2) for starting the vacuum suction from the mold to closely bring the thermoplastic resin foamed sheet 1 into contact with the mold so that the recessed part becomes a hermetically closed state, a process (3) for supplying the thermoplastic resin to the recessed part through the resin passage provided in the mold simultaneously with or after the start of vacuum suction in the process (2) to integrally weld the molten thermoplastic resin to the thermoplastic resin foamed sheet 1 and a process (4) for stopping the vacuum suction simultaneously with or after the stop of the supply of the molten thermoplastic resin to eject the molded product.
