PROBLEM TO BE SOLVED: To provide an RTM process which can cope with mass production and develops no wrinkles. SOLUTION: A plurality of layers of reinforced fiber fabrics 1a placed at a desired lamination angle are stacked, and the reinforced fiber fabrics 1a are continuously or intermittently connected at the part of first contact with the upper die. Connecting a reinforced fiber at the part of first contact with the upper die causes excellent handling, allows the reinforced fiber fabric connected with a plurality of layers whose respective layers have constant and stable tension, and a shaping property even if the respective layers are drawn in a direction of a connection part when being pressed by the upper die and a curvature is different on two sides of a product to be obtained, and obtainable an RTM molding without the "wrinkle" of the reinforced fiber to be obtained.
