摘要: A golf club shaft which satisfies strength and is lightweight is provided by the present invention. This golf club shaft comprises one or more fiber-reinforced resin layers, and is characterized by satisfying the following relationship (1), wherein x [mm] is the displacement in a cantilever bending test, M [g] is the mass of the golf club shaft, and L [mm] is the length thereof, and by satisfying the following strength standard values [1]-[4]: M×(L/1168)
