PROBLEM TO BE SOLVED: To provide a manufacturing method of a fiber reinforced resin molded article which does not need a prior defoaming of the resin and is able to produce a reinforced resin molded article having a higher Vf and better quality compared with that made by the LRTM method. SOLUTION: A mold 11 in which a reduced pressure channel 15 is formed at the out side of a cavity 14 so as to surround the cavity 14 at the same time the mold is clamped at a state where a member for deaerating 18 is arranged so as to mount the cavity 14 and a part of the reduced pressure channel 15 is used. The inside of the cavity 14 is evacuated through the reduced pressure channel 15 at a state where a reinforcing fiber substrate 30 ia arranged in the cavity 14, at the same time the reinforcing fiber substrate 30 is immersed with a resin by injecting the resin into the cavity 14 through an injecting port 19 communicating to with the cavity 14. The resin is injected into the cavity 14 under the first pressure, after gelation of the resin injected into the cavity 14 started to be gelled, the resin is injected by enhancing the injecting pressure of the resin at the second pressure higher than an injecting pressure in the case of the LRTM method.
