To obtain a tube with a flexural rigidity difference in the circumferential direction reduced without lowering flexural rigidity in the tube having an axial length direction reinforcing fiber layer.

The tube has one axial length direction fiber layer by two fiber-reinforced resin sheets 8 and 9 in which reinforcing fibers are arranged in the axial length direction of the tube, one side in the longitudinal direction is made axial length direction sides 8a and 9a in the axial length direction, and another side in the longitudinal direction is made slanted sides 8b and 9b slanted to the axial length direction. The two resin sheets 8 and 9 are butted to the slanted sides 8b and 9b of the two fiber-reinforced resin sheets 8 and 9, and the axial length direction sides 9a and 8a of the other fiber-reinforced resin sheet are butted and wound every half circumference to form the axial length direction fiber layer.
