Provided is a method of producing a fluorosilicone rubber laminate. The method comprises: (1) applying a primer composition onto a substrate, and forming a primer layer on a surface of the substrate; and (2) bringing a fluorosilicone rubber composition into contact with the primer layer, and adhering a fluorosilicone rubber to the primer layer. The fluorosilicone rubber composition comprises a platinum-based catalyst and/or a fluorosiloxane containing a silicon atom-bonded hydrogen atom. The primer composition comprises a platinum-based catalyst or a fluorosiloxane containing a silicon atom-bonded hydrogen atom, however the primer composition does not simultaneously comprise a platinum-based catalyst and a fluorosiloxane containing a silicon atom-bonded hydrogen atom. Either the primer composition or the fluorosilicone rubber composition comprises a platinum-based catalyst or a fluorosiloxane containing a silicon atom-bonded hydrogen atom. A laminate in which a fluorosilicone rubber layer and a base material are favorably adhered to each other can be obtained.
