PROBLEM TO BE SOLVED: To provide an injection molding mold capable of advantageously preventing a flow mark from being formed on the design surface of a resin molded article to be molded by a simple structure. SOLUTION: The injection molding mold is constituted so that an injection gate 66 having the substantially same flow channel cross-sectional area as an opening area of a gate port 72 and a runner 64 having a flow channel cross-sectional area larger than the flow channel cross-sectional area of the injection gate 66 are arranged to cross each other at a right angle.
