A production method of a golf club shaft made of a fiber-reinforced resin according to the present invention comprises the steps of driving and rotating a shaft substrate made of an uncured fiber-reinforced resin on the axis thereof, moving a plurality of creel stands in parallel in the axial direction of the shaft substrate, and feeding out tapes from a plurality of the creel stands and winding and laminating the tapes simultaneously and spirally on the outermost layer of the shaft substrate for integrally molding them while the rotating speed of the shaft substrate and the moving speed of the creel stands are being controlled simultaneously. An apparatus for producing a fiber-reinforced resin golf club shaft according to the present invention comprises a support shaft for supporting a cylindrical shaft substrate molded from an uncured fiber-reinforced resin, a driving motor for driving and rotating the support shaft, a feed screw disposed in parallel with the support shaft, another driving motor for driving and rotating the feed screw, different from the driving motor, a plurality of nuts meshing with the feed screw, creel stands for tapes made of organic polymers, supported by the nuts, respectively, still another driving motor for driving and rotating a part of a plurality of the nuts, different from the two driving motors, and a controller for controlling the rotating speed of each of the driving motors.
