PROBLEM TO BE SOLVED: To provide a technique capable of finishing the design surface of a resin molded product so as to have an intended shape over a wide range even if the resin molded product has the rib protruded from its non-design surface. SOLUTION: This injection mold 31 is used for injection-molding the resin molded product having the design surface and the non-design surface and having the rib protruded from its non-design surface. Cavities 27 and 28, which form the shape corresponding to that of the ribbed resin molded product are formed in the injection mold 31. Flow channels 43 and 44, which are opened to the surface of a cavity for molding the leading end surface of the rib at its one end and communicate with the outside of the mold at its other end, are formed to the injection mold 31.
