ABSTRACT:
In the manufacturing method of the laminated metal plate, a fluorine resin film is used as a plastic film. Prior to a flame treatment, a joint surface of the metal plate is heated with a direct flame of 900° C. to 1200° C. for 1 to 5 seconds so that the joint surface is preheated to 40° C. to 70° C. After that, the joint surface of the metal plate is heated to 250° C. to 450° C. by the follow-on flame treatment.
