PROBLEM TO BE SOLVED: To provide a molding method of an FRP hollow structure which enables the stable molding of an FRP hollow structure using an expansible and contactable hollow core and enables the enhancement of molding efficiency due to voidless molding while dispensing with finish processing such as repairing or the like and reducing the load of finish processing. SOLUTION: In the molding method of the FRP hollow structure by arranging the hollow core having a reinforcing fiber base material arranged to its outer periphery in the cavity of a mold composed of a plurality of molds and injecting a resin in the mold while pressurizing the inside of the core after mold clamping to mold the same, the non-arranging part of the reinforcing fiber base material to the hollow core is provided in the cavity.
