    Abstract: The invention provides a laminate in which a fluororesin layer and a rubber layer are firmly bonded to each other and the fluororesin layer has low fuel permeability and is less likely to suffer solvent cracking. The laminate includes a rubber layer (A) and a fluororesin layer (B). The fluororesin layer (B) contains a copolymer containing a chlorotrifluoroethylene unit, a tetrafluoroethylene unit, and a perfluoroalkyl vinyl ether unit. The copolymer contains 96.0 to 97.4 mol % of the chlorotrifluoroethylene unit and the tetrafluoroethylene unit relative to all the monomer units constituting the copolymer and 2.6 to 4.0 mol % of the perfluoroalkyl vinyl ether unit relative to all the monomer units constituting the copolymer.
