PROBLEM TO BE SOLVED: To provide a multi-layer resin tube in which penetration of organic solvents into a resin tube can be prevented, and in which construction time is shortened. SOLUTION: The outer side of a polyolefin resin in a major layer is coated with a barrier layer through which organic solvents cannot penetrate. The outer side of it is coated with a protective layer to prevent UV-deterioration, contamination, or generation of flaws. It is thus provided without being attached to the major layer, so that it can be easily removed. Barrier performance and protective performance can be maintained for a long period.
