PROBLEM TO BE SOLVED: To provide a manufacturing method of fiber-reinforced plastics with advantages such as successful fluidity/molding follow-up properties of complicated shape, and excellent mechanical characteristics, low variability and dimensional stability, when the fiber-reinforced plastic products are manufactured. SOLUTION: The fiber-reinforced plastic products are molded through the sequence of at least the following processes (1) to (3): (1) a lamination process to obtain a laminate by laminating a plurality of prepreg base materials in the way that an area where only the deeply cut prepreg base material with the reinforcing fiber split to the length of 10 to 100 mm, is formed on at least, a part of the laminate, (2) a molding process to arrange the above area in the double contour part of the molding die and mold the laminate with the above area stretched along the double contour part, and (3) a process to unload the fiber-reinforced plastic products from the molding die.
