In a golf club shaft hollow pipe-shaped and composed of a laminate of prepregs, a vibration absorption member (10) made of an elastic material whose tandelta at 10° C. is not less than 0.7 is installed at least one portion inside the hollow pipe-shaped golf club shaft. The vibration absorption member (10) has a body having a hollow portion, a central part connected to the body through a plurality of connection parts and disposed inside the hollow portion, a plurality of projected parts formed on a peripheral surface of the body and contacting an inner peripheral surface of the pipe-shaped golf club shaft. It is preferable that the weight of the vibration absorption member (10) is not less than 1 g nor more than 10 g, that the number of the connection parts is not less than two nor more than 10, and that the weight of the central part is not less than 10 wt % nor more than 60 wt % of a whole weight of the vibration absorption member.
