1. A laminate comprising:
a fluoroelastomer layer (A); and
a fluororesin layer (B) stacked on the fluoroelastomer layer (A),
the fluoroelastomer layer (A) being a layer formed from a fluoroelastomer composition,
the fluoroelastomer composition containing a fluoroelastomer, a basic multifunctional compound, and at least one compound (a) comprising a fluororesin (a1) and a phosphorus compound (a2),
the fluororesin (a1) being at least one selected from the group consisting of non-melt processible polytetrafluoroethylene, low molecular weight polytetrafluoroethylene, a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer, a tetrafluoroethylene/hexafluoropropylene copolymer, an ethylene/tetrafluoroethylene copolymer, an ethylene/tetrafluoroethylene/hexafluoropropylene copolymer, polychlorotrifluoroethylene, a chlorotrifluoroethylene/tetrafluoroethylene copolymer, an ethylene/chlorotrifluoroethylene copolymer, polyvinyl fluoride, and a fluoromonomer/vinyl ester copolymer, the phosphorus compound (a2) being at least one selected from the group consisting of a phosphine oxide, and a phosphine compound represented by PR3, wherein three Rs are the same as or different from each other, and are each a halogen atom or an organic group, and at least one R is a halogen atom or a C1-C30 hydrocarbon group containing a substituent wherein the substituent is at least one selected from the group consisting of an alkoxy group, an amino group, a cyano group, an aldehyde group, a carboxylic acid group, a halogen atom, a phosphino group, a phosphono group, and a diphenylphosphino group,
the compound (a) being present in an amount of 0.01 to 120 parts by mass relative to 100 parts by mass of the fluoroelastomer,
the fluororesin layer (B) being formed from a fluororesin (b1) having a fuel permeability coefficient of 2.0 g·mm/m2/day or lower.
