Summary:PROBLEM TO BE SOLVED: To provide a resin tube excellent in thermal resistance and chemical resistance and easy to be disposed of as well as incineration processing. SOLUTION: A resin tube 1 is constituted in two layers of an outside layer 2 and an inside layer 3. The outside layer 2 is constituted of polyethylene having MFR of 0.1-1.5 and density of 0.940-0.970 or low density polyethylene or linear low density polyethylene MFR having of 0.2-10 and density of 0.918-0.940, and the inside layer 3 is constituted of metallocene polyethylene having density of 0.860-0.910 provided by a metallocene catalyser or polyethylene containing 50 weight % or more of metalocene polyethylene.
