PROBLEM TO BE SOLVED: To provide a multilayer tube suppressing an occurrence of delamination between respective layers and excellent in durability. SOLUTION: This multilayer tube 10 has a three-layer structure including an inner layer 12 comprising a copolymer fluororesin, an interlayer 14 comprising a blended resin formulated with an ethylene copolymer resin at least containing glycidyl methacrylate and an acid-modified polyolefin resin outside the inner layer 12, and an outer layer 16 comprising a polyurethane resin outside the interlayer 14. As the inner layer 12, for example, a copolymer fluororesin consisting of tetrafluoroethylene, vinylidene fluoride and hexafluoropropylene or the like is used. The occurrence of delamination between respective layers is suppressed by providing the interlayer 14 between the inner layer 12 and the outer layer 16. COPYRIGHT: (C)2008,JPO&INPIT
