PROBLEM TO BE SOLVED: To form a product having a well-formed appearance by dispersing a rigid reinforcing agent by generating a turbulent flow in a resin material. SOLUTION: In a structure of a resin material injection unit 5 of a mold 1 for injection molding having a sprue 6, a runner 7 and a gate 8 to inject a resin material containing the rigid reinforcing agent in a product molding part 4 of the mold, a volume 11 having a width and a vertical section larger than the runner 7 for generating the turbulent flow in the resin material flowing to the runner is formed between the runner 7 and the gate 8.
