Abstract
The invention provides a laminate including a fluoroelastomer layer and a fluororesin layer which are firmly bonded to each other. The laminate includes a fluoroelastomer layer (A) and a fluororesin layer (B) stacked on the fluoroelastomer layer (A). The fluoroelastomer layer (A) is a layer formed from a fluoroelastomer composition. The fluoroelastomer composition contains a fluoroelastomer, a basic multifunctional compound, and at least one compound (a) selected from the group consisting of a fluororesin (a1) and a phosphorus compound (a2). The compound (a) is 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) is formed from a fluororesin (b1) having a fuel permeability coefficient of 2.0 g·mm/m2/day or lower.
