A shafthas layers. The layers include a straight layer in which an absolute angle θa of a fiber to a shaft axis line is 10 degrees or less, 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 80 degrees or greater. The layers include full length layers and a partial layer. The full length layers include full length bias layers and full length straight layers. 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.
