Claim:
A golf club shaft comprising a plurality of layers, wherein the layers comprise a straight layer in which an absolute angle θa of a fiber to a shaft axis line is equal to or less than 10 degrees, a bias layer in which the angle θa is 30 degrees or greater and 60 degrees or less, and a hoop layer in which the angle θa is equal to or greater than 80 degrees; the layers comprise full length layers disposed all over in a longitudinal direction of a shaft, and a partial layer partially disposed in the longitudinal direction of the shaft; the full length layers comprise full length bias layers as the bias layer, and full length straight layers as the straight layer; the full length bias layers are located on the innermost side among the full length layers; the full length layer brought into contact with a low RC full length layer outside the full length bias layers is a high RC layer; the full length layer brought into contact with an outer surface of the full length bias layers is a high RC layer; wherein the high RC layer is a layer formed by a prepreg having a resin content equal to or greater than 24% by mass; and the low RC layer is a layer formed by a prepreg having a resin content equal to or less than 20% by mass.
