PROBLEM TO BE SOLVED: To provide a method for manufacturing an FRP molding which no longer shows an appearance failure generated by pinholes or a cavity and has a boss or a rib on the outside of a bottom. SOLUTION: In the method for manufacturing an FRP molding (a bathtub) having a boss or a rib formed on the outside of the bottom by loading a material for a fiber-reinforced resin molding into a mold 10 and thermally pressure molding the material, a part 21 of the material for a fiber-reinforced resin molding is loaded into a recessed part 13 for forming the boss or the rib of the mold 10 and the remainder 22 of the material for the fiber-reinforced resin molding, is loaded over the part 21. The FRP molding (the bathtub) is of such a type that a bend part or an almost right-angled angular part, for example, is present at two or more spots. The figure 14 indicates the bend part for forming the edge part (a framework) of the bathtub formed in the top force 11 and the figure 15 indicates the bend part for forming an arm rest of the bathtub formed in the top force 11 and further, the figure 20 indicates a bathtub molding before releasing from the mold 10.
