PROBLEM TO BE SOLVED: To provide an FRP manufacturing method capable of allowing a resin to flow through a normal resin flow channel in a normal flow rate by preventing the short pass of the resin toward a vacuum suction port to prevent the non-impregnation of a molded product with the resin. SOLUTION: The FRP manufacturing method is composed of at least a setting process (A) for installing a preform 2 comprising a reinforced fiber base material, a vacuum suction port 6 and a resin injection port 4 on a mold 1, a hermetically closing process (B) of a suction part for connecting the preform 2 and the vacuum suction port 6 by a ventilation material 7 and subsequently sealing the whole of the vacuum suction port and at least a part of the ventilation material 7 by an airtight material 9 to cover them, a hermetically sealing process (C) for sealing and covering the whole of the preform 2 on the mold, the vacuum suction port 6, the resin injection port 4, the ventilation material 7 and the suction port covering molding part with a bag material 10 to hermetically close the same, a vacuum process (D) for evacuating the whole of the molding part sealed and covered with the bag material 10 by the suction from the vacuum suction port 6 and a resin impregnating and curing process (E) for injecting a resin from the resin injection port 4 to impregnate the reinforcing fiber base material 2 with resin to cure the resin.
