PROBLEM TO BE SOLVED: To provide an FRP waterproof apparatus such as a heat resistant and anticorrosive waterproof pan and a roof drain usable for high temperature asphalt waterproofing and FRP waterproofing; and a female screw socket for reinforcing a screw part by glass fiber, in a waterproofing technology of a water quality requiring anti-corrosiveness, in a hot spring, various water treatment facilities and a chemical plant. SOLUTION: In an RTM method (a resin transfer mold) for pressing a heat resistant resin in a mold together with the glass fiber or FRP using a similar composition technology, strength is provided by increasing the content of the glass fiber by strengthening the screw part by the glass fiber. An FRP waterproof pan, the roof drain and a screwing-in socket generally usable for the various water treatment facilities of a corrosive fluid and causing nout electric corrosion, can be manufactured by forming an integral mold without exposing fiber of the glass fiber to a surface.
