PURPOSE: To provide a producting method of a golf clubshaft having a better production efficiency in comparison with one produced by a conventional inner pressure molding method or one of inner pressure holding tube.

CONSTITUTION: This method is composed of a melting process of vinyl chloride resin with a plasticizer, a process in which molton fluid is conducted to the surface of a hollow mandrel 1 having air exhaust hole 11 and a vinyl chloride film 2 is formed, a process in which a prepreg 3 is wound up on the vinyl chloride resin film, a setting process of the rolled article to a molding frame 4, and a heating and molding process by injecting air from the hollow made in the mandrel 1.
