PROBLEM TO BE SOLVED: To enhance an interlayer adhesion force of a laminated type fuel tube 1, and improve fuel barrier property. SOLUTION: An inner layer 2 is made to be a fluorine-containing ethylenic polymer layer, and the outside layer 3 is made to be a semi-aromatic amorphous polyamide-based resin layer. The fluorine-containing ethylenic polymer layer and the semi-aromatic amorphous polyamide-based resin layer are directly chemically bonded at least by an amine functional group.
