A golf club shaft includes a tip end, a butt end, a first anisotropic portion that is twisted in a first direction in conjunction with a bending of the golf club shaft at a circumferential bending position, and a second anisotropic portion that is twisted in a second direction in conjunction with the bending. The second anisotropic portion is located on a tip end side relative to the first anisotropic portion. The second direction is opposite to the first direction. In the shaft, the twist accompanied by the bending in the first anisotropic portion can be offset by the twist accompanied by the bending in the second anisotropic portion.
