PROBLEM TO BE SOLVED: To provide a manufacturing method for a molding made by providing a thermoplastic resin member on a thermoplastic resin sheet, excellent in the homogeneity of drawing strength. SOLUTION: The manufacturing method for the thermoplastic resin molding made by partially fusion-bonding a functional member of a thermoplastic resin on a shaped thermoplastic resin foam sheet comprises: the process (1) of feeding the thermoplastic resin foam sheet 2 shaped in a desired shape in advance between a pair of dies 6 and 9 at least one of which has a recess 12 of the shape same as that of the functional member; the process (2) of closing the dies and blocking the opening of the recess with the thermoplastic resin foam sheet; the process (3) of feeding a molten thermoplastic resin to the recess through a resin passage 13 formed in the dies in communication with the recess, with the dies being closed and the opening of the recess being blocked with the thermoplastic resin foam sheet to fuse and integrate the thermoplastic resin with the foaming sheet; the process (4) of cooling the thermoplastic resin molding formed by the process (3) and removing it from the dies.
