PROBLEM TO BE SOLVED: To reduce weight so as to improve handleability by integrally arranging a supporting column part and an arm part bent and extended from the supporting column part in molding of a FRP-made bent supporting post suitable for various building structures and for a supporting post for an advertisement, a sign, or the like. SOLUTION: An FRP-made bent supporting post 1 is molded by integrally arranging a supporting column part 2 and an arm part 3 bent and extended from the supporting column part 2. In this process, a reinforced fiber base material is arranged around a core material having a resin flow passage formed on the surface so as to be inserted into a die having a bent cavity, and then, the inside of the die is evacuated and resin is injected so as to be scattered on the surface of the reinforced fiber base material and so as to be impregnated into the reinforced fiber base material, and consequently, the supporting column part 2 and the arm part 3 are molded integrally. In this kind of the FRP-made bent supporting post 1, a flange member 4 used for mounting and fixing it to a base or the like is arranged in the lower end part of the supporting column part 2 desirably. The flange member 4 is molded separately from the supporting column part 2, and then, connected to the supporting column part 2 by adhesion or fastening.
