PROBLEM TO BE SOLVED: To solve the problem that a resin is apt to easily accumulate in a recessed part to be formed in the bent part of a molded product due to lack of consideration when the resin is injected and consequently, defects such as the generation of cracks inside the resin easily occur, in a molding method for the recessed part in an FRP structure to be molded by a conventional vacuum impregnation molding method. SOLUTION: In the method for molding the molded product by injecting the resin after covering a loaded object in a molding tool doubly with a vacuum film and degassing the interior of the vacuum film, a local cover plate is formed in the recessed part to be formed in the bent part of the FRP molded product over the first vacuum film directly covering the loaded object. Further, the second vacuum film covering the first vacuum film is internally degassed then the cover plate is pressed from outside the second vacuum film and the resin is injected into the area covered by the first vacuum film.
