A golf club shaft 2 made of a fiber-reinforced resin having a weight W of 30 to 55 g calculated as a shaft having a length of 46 inches and an average flexural rigidity EIa of 1.5 to 4.0 kgf.m<SUP>2 </SUP>and satisfying the equation: EIa>=0.1W-1.5. Since it is light weight but has a relatively high flexural rigidity, a golf club can be swung at high speed without deteriorating the flight direction performance.
