PROBLEM TO BE SOLVED: To provide an RTM molding method which can greatly simplify the structure of a mold, to reduce a processing cost and can efficiently and promptly form even an FRP molding having an undercut shape. SOLUTION: In the RTM molding method, a reinforcing fiber substrate is arranged in the cavity part of the mold composed of a plurality of molds including first and second molds arranged opposite to each other, after mold clamping, when the FRP molding is molded by injecting a resin, an intermediate member which is formed in advance in a shape to parallel the shape of the molding is set between the first mold and the second mold, a pressurized medium is filled between the intermediate member and the second mold, the reinforcing fiber substrate is arranged between the intermediate member and the first mold, and the resin is injected.
