<p>[Problem] To provide a corrugated tube with which mutually opposing ridge parts and mutually opposing valley parts can be fitted together easily when both end parts of the tube between which a slit is sandwiched are overlapped, and thus to improve the work of fitting together the parts. [Solution] A tube main body (2) is formed with multiple connected ridge parts (2a) and valley parts (2b) which alternate in the longitudinal direction Y1. A slit (3) is provided in this tube main body (2) in the longitudinal direction Y1, and both end parts of the tube main body (2) between which the slit (3) is sandwiched overlap each other. Marks (4) are provided on only one of the multiple ridge parts (2a) on both end parts between which the slit (3) is sandwiched.</p> |
