PURPOSE:To obtain a large number of resin moldings by using only one master mold in a short time by method in which a production mold containing a granular substance is formed by using a master mold, a fiber-reinforced material is closely bonded to a given position of the production mold, defoamed, and hardened, and the solidified state of the granular substance is released. CONSTITUTION:A frame with a suction tube 7 is set on the upside of a master mold 1, a granular substance 10 is packed into the frame, and a shield film 9 is covered on the frame and sucked to reduce the pressure for solidifying the granular substance to obtain a production mold P. A liquid resin 11 for molding and a fiber reinforcing material 12 are alternately laminated on a given position of the mold P and pressed by a roller. After the resin is hardened, the solidified state of the granular substance is released to take out a molding.
