摘要： Provided are tubular carbon fiber reinforced composite material and having excellent cylindrical bending strength and a golf club shaft using the same. This tubular carbon fiber reinforced composite material is formed by laminating and curing a straight layer and a bias layer. The straight layer comprises carbon fibers S coated with a sizing agent S and arranged in parallel in a direction of -20° to +20° with respect to the axis of the tubular body, and contains a thermosetting resin S. The bias layer comprises carbon fibers B coated with a sizing agent B and arranged in parallel in a direction of +25° to +65° with respect to the axis of the tubular body, and contains a thermosetting resin B. The carbon fiber reinforced composite material constituting the bias layer has an interlaminar shear strength of not less than 110 MPa. A cured product of the thermosetting resin S has an elastic modulus of not less than 4.0 GPa.
