The laminate according to the present invention 1 has an acrylic elastomer layer 11 and a fluorine elastomer layer 12 that are bonded to each other. The acrylic elastomer layer 11 is made of an acrylic elastomer composition having an epoxy group-containing acrylic elastomer and an onium salt added and the fluorine elastomer layer 12 is made of a fluorine elastomer composition having a fluorine elastomer and a polyol crosslinking agent added. In the laminate 1 , the elastomer layers are bonded tightly to each other even without any surface treatment.

Claims (4)
