PROBLEM TO BE SOLVED: To provide a method for manufacturing a thermoplastic resin-made belt with teeth which prevents disorder of a core with wound around an inner mold caused by injection pressure during injection-molding the thermoplastic resin. SOLUTION: A method for manufacturing a thermoplastic resin-made belt with teeth comprises a process of injection-molding a thermoplastic resin to form a resin layer 15 on an inner mold 3, a process of making cuts 27a and 27b in the circumferential direction at the both edges of the resin layer 15, a process of pushing a wind-beginning portion 29 of a core wire into the cut 27a at one edge portion 27a for fixing it, winding the core wire 16 around the circumferential surface of the resin layer 15 and pushing the wind-finishing portion 30 into the cut 27b at another edge portion 27b for fixing it, a process of placing the inner mold 3 again within the outer molds 2a and 2b and then injection-molding the thermoplastic resin to form a back surface 17 of the belt and a process of cutting the obtained sleeve into a predetermined width to produce a belt with teeth.
