PROBLEM TO BE SOLVED: To provide a multi-layer tube suppressing generation of each interlaminar releasing and superior in durability. SOLUTION: The multi-layer tube 10 has a three-layer structure equipped with an inner layer 12 consisting of a polyolefin resin, an intermediate layer 14 consisting of an adhesive polyolefin resin on the outside of the inner layer 12, and an outer layer 16 consisting of a polyurethane resin on the outside of the intermediate layer 14. As the inner layer 12, for example, a polyethylene resin is used, and as the intermediate layer 14, for example, an acid-modified polyolefin resin or the like is used. COPYRIGHT: (C)2008,JPO&INPIT
