Abstract: A shaft 6 has a plurality of full length layers s2, s3, and s6 to s9. The full length layers have full length bias layers s2 and s3, and full length straight layers s6, s8, and s9. The full length straight layers s6, s8, s9 located outside the full length bias layers s2 and s3 include a novolac-containing layer. In the novolac-containing layer, a content Rn of the novolac type epoxy resin is 3% by mass or greater and 19% by mass or less. If an average specific gravity of the novolac-containing layers constituting the full length straight layers is defined as S1, and an average specific gravity of the full length bias layers and inside of the full length bias layers is defined as S2, the specific gravity S1 is greater than the specific gravity S2.
