PROBLEM TO BE SOLVED: To provide an RTM method which enables a high-speed molding even for a relatively large molding article without generating the region having no inflow of a resin and thereby, enables shortening of a molding time, increase of production and reduction of production cost. SOLUTION: The RTM method enables molding by arranging a reinforcing fiber substrate in the cavity of a molding die comprising a plurality of dies, clamping, injecting the resin and then molding. In this case, an intermediate member which forms the flow path of molten resin is arranged between one die (e.g. an upper die) and the other die (e.g. a lower die), and the resin is injected into the reinforcing fiber substrate approximately at the same time from a plurality of places through the intermediate member.
