PROBLEM TO BE SOLVED: To manufacture a branched part of a tube made of a fiber-reinforced resin whose outer shape is highly accurately molded. SOLUTION: When the branched part of the tube made of the fiber-reinforced resin is manufactured by molding a mandrel 10 corresponding to a male mold into a hollow elastic body and curing a raw material 13 comprising a reinforcing fiber-containing resin and the like filled between the mandrel 10 and a female mold 14 made of a metal, a pressurized gas is fed into a hollow part 10a of the mandrel 10 to expand and deform the mandrel 10, and the raw material 13 is pushed outward, and the outer shape of the raw material 13 is highly accurately molded by receiving a counterforce of the female mold 14.
