PROBLEM TO BE SOLVED: To provide a waste liquid conducting tube collectively having elasticity and water content evaporation preventive capacity without increasing the number of parts. SOLUTION: Along a longitudinal direction of an inner peripheral surface of an elastic tube body (1) comprising a rubber-like elastic body, a polymer whose moisture permeability is lower than the rubber-like elastic body, in particular a thin film of a fluoropolymer (2) is intermittently bonded.
