Claim:
A hose comprising: an inner layer comprising a fluorocopolymer and an outer layer comprising a polyamide, wherein the inner layer is laminated to the outer layer, the fluorocopolymer comprises, based on the total number of mols of the repeating units: from 50 to 99.89 mol % of repeating units (a) based on tetrafluoroethylene and/or chlorotrifluoroethylene, from 0.01 to 5 mol % of repeating units (b) based on a cyclic hydrocarbon monomer having a dicarboxylic anhydride group and having a polymerizable unsaturated group in the ring, and from 0.1 to 49.99 mol % of repeating units (c) based on a fluoromonomer which is not tetrafluoroethylene or chlorotrifluoroethylene, and a flow coefficient of the fluorocopolymer is in the range from 0.1 to 1,000 mm 3 /sec.
