PROBLEM TO BE SOLVED: To provide a corrugated tube and the like excellent in wire insertion workability.SOLUTION: One end portion of an inner member 3 is connected to a hinge section 7. A predetermined range of the inner side member 3 from a joint to the hinge section 7 is a curved portion 17. The curved portion 17 has a constant curvature radius C. A region extending from the other end portion of the inner member 3 toward a tube opening portion is a linear portion 25. The linear portion 25 of the inner member 3 is referred to as extension portion 27. In the present invention, in a state before the inner member 3 and an outer member 5 are closed, an opening dimension between an end portion of the extension portion 27 of the inner member 3 and the hinge section 7 is larger than that between an end portion of an extension portion 23 (curved portion 21) of the outer member 5 and the hinge section 7. Furthermore, the opening dimension between the end portion of the extension portion 23 of the outer member 5 and the hinge section 7 is larger than a twofold of the curvature radius C of the curved portion 17 of the inner member 3.
