    摘要: A metal laminate having high thermal stability is produced by forming a cured film layer of a thermally stable heterocyclic polymer such as polyamide imide having only a small volatile content on at least one surface of one or both of metal plates or foils such as aluminum, separately forming an adhesive layer of a thermally stable heterocyclic polymer having a thickness of one-third or less of the above film layer and containing a volatile matter in an amount of not more than 20% by weight, and then heat bonding both of the metal plates or foils through the above adhesive layer with the film layer being allowed to face the adhesive layer. The metal plates and foils are mutually insulated.
