PROBLEM TO BE SOLVED: To provide a resin tube which is low in permeability of a usual gasoline as well as an alcohol contained fuel, having highly sufficient adhesiveness between a barrier layer (a permeability shutoff layer) and a protecting layer (a coating layer for the permeability shutoff layer), facilitating the reuse of end materials and having low cost material construction. SOLUTION: The resin tube comprises laminated tubular resin layers, at least one of the layers being formed mainly of a PBT, PBN, PET or PEN resin and the others being formed mainly of PBT copolymers. The PBT copolymer is made to contain an acid component and a glycol component. |
