A bent part of a shaft-shaped composite member is formed by stacking a 0° layer located on a radial outer side and having a carbon fiber orientation direction parallel to an axial direction of the shaft-shaped composite member and a ±45° layer located on a radial inner side and having a carbon fiber orientation direction obliquely intersecting the axial direction of the shaft-shaped composite member. A stress relaxation layer is interposed between the 0° layer and the ±45° layer. The stress relaxation layer is set to have a flexural rigidity lower than a flexural rigidity of the 0° layer and a torsional rigidity lower than a torsional rigidity of the ±45° layer.
