PROBLEM TO BE SOLVED: To facilitate the gradual reduction in the wall thickness of the end part region of a reinforcing layer by almost turning the reinforcing fibers of the reinforcing layer in the circumferential direction of a tubular member, to prevent the sudden change of a cross section state, to make the reinforcing fibers of a main body hard to twist and to prevent the molding bending of the tubular member. SOLUTION: This tubular member containing a synthetic resin as a matrix and reinforced by reinforcing fibers contains reinforcing fibers 12S arranged in the vicinity of the end part of the main body layer 10J continued from the inward part in the axial direction of the tubular member to the end part thereof and almost turned in the circumferential direction of the end part as a main component and has a reinforcing layer 12H wherein the end part region 12K on the side of the inward part is gradually reduced in thickness toward the inward part over the axial direction length L equal to or more than the wall thickness dimension (t) in the vicinity of the other end part of the layer 12H. |
