PROBLEM TO BE SOLVED: To achieve the shortening of a work time required in molding and to especially easily obtain a fiber-reinforced resin molded product of good quality sufficiently developing advantages possessed by a reinforcing fiber in the shortest resin injection time. SOLUTION: A reinforcing fiber base material layer 2 is formed on a mold 1 and a resin diffusing net 4 for accelerating the diffusion of an injection resin is laid on the upper surface of the reinforcing fiber base material layer 2 to cover the mold with the reinforcing fiber base material layer 2 and the resin diffusing net 4 using a bag film 6 to form a molding part. Further, a vacuum hose 7 for internal evacuating the molding part is arranged to the periphery of the reinforcing fiber base material layer 2. Herein, the distance L from the side edge part of the reinforcing fiber base material layer 2 to the vacuum hose 7 is set to 50 mm or above. Then, the resin is injected from an injection pipe 5 under a reduced pressure environment due to vacuum suction and the reinforcing fiber base material layer 2 is impregnated with the injection resin to obtain the fiber reinforced resin molded product.
