A method of producing a heat-resisting flexible laminate sheet able to prevent a defective appearance such as wrinkles and corrugations and improve dimension stability. A method of producing a flexible laminate sheet having a metal foil (B) pasted to at least one surface of a heat-resisting adhesive film (A), characterized by comprising the step of heat-laminating the heat-resisting adhesive film (A) and the metal foil (B) between at least one pair of metal rolls via a protection film, the step of slowly cooling a laminate consisting of the film (A), the foil (B) and the protection film, and the step of separating the protection film. The slowly cooling step is preferably carried out by providing a heating mechanism set to temperatures lower than a metal roll surface temperature, especially a slow-cooling roll. The surface temperature of the slow-cooling roll is preferably set 50°C- 250°C lower than the surface temperature of the metal roll. |
