Provided are: an FRP sheet press molding method and device whereby yield can be improved without opening/closing adjustment of a mold after mold clamping; and an FRP molded article. The FRP sheet press molding method, whereby a press-molded article PM is molded using a fiber-reinforced plastic sheet material SM, comprises: a press step in which molds 2, 3 are closed and the heated sheet material SM is press-molded inside a cavity 5; and a filling step in which the closed state of the molds 2, 3 is maintained from the press step, a molten resin MP is pressure-injected into a gap IS that occurs between the sheet material SM and the cavity 5, and a surface of the sheet material SM and a surface of the molten resin MP are caused to come in contact with the cavity 5.
