The present invention relates to a laminate including a fluororubber layer (A) and a fluororesin layer (B) stacked on the fluororubber layer (A). The fluororubber layer (A) is a layer formed from a fluororubber composition. The fluororubber composition contains a fluororubber (a1) and a basic multifunctional compound having at least two nitrogen atoms in the molecule with a distance between the nitrogen atoms in the molecule of 5.70 Å or greater. The fluororubber (a1) has an absorption coefficient at 1720 cm−1, determined after being brought into contact with triethyl amine, of 0.35 or lower.
