PROBLEM TO BE SOLVED: To provide a mold capable of easily imparting a sound absorbing capacity without modifying prefoamed particles or requiring the post processing of a molded product, in a manufacturing method of a thermoplastic foamed resin molded product molded by in-mold foam molding. SOLUTION: In the mold constituted for synthetic resin in-mold foam molding so that the molding space, which is demarcated by one set of molds composed of a core mold and a cavity mold, is filled with prefoamed particles and the prefoamed particles are heated by a heating medium to be foamed and welded to obtain a foamed molded product, a plurality of plate-like members for providing grooves to the molded product are arranged to at least one of one set of the molds.
