Zusammenfassung:	A die for molding a reinforcing bar, which enables the production of a reinforcing bar having sufficient strength in a convenient and inexpensive manner, includes: a main flow channel (F1), formed in a central portion of a main body, that receives a molten thermoplastic polymer material (Rt) output from an extruder (2); at least one first sub flow channel (F2), formed in an outer peripheral portion of the main body, that receives the molten thermoplastic polymer material (Rt) and fluidly connects with an outer peripheral portion in the main flow channel (F1); and at least one second sub flow channel (F3) configured to receive reinforcing fibers (4) and fluidly connected with the main flow channel F1 upstream of a junction position of the main flow channel F1 and the at least one first sub flow channel (F2).
