A method for producing a heat-resistant flexible laminate in which appearance defects, such as wrinkles and waviness, can be prevented and dimensional stability can be improved is provided. A method for producing a flexible laminate including a heat-resistant adhesive film (A) and a metal foil (B) bonded to at least one surface of the heat-resistant adhesive film (A) includes a step of performing thermal lamination by passing the heat-resistant adhesive film (A) and the metal foil (B) between at least one pair of metal rollers through a protective film; a step of slowly cooling a laminate including the heat-resistant adhesive film (A), the metal foil (B), and the protective film; and a step of separating the protective film. The slow cooling step is preferably performed by providing a heating mechanism, in particular, a slow-cooling roller, of which temperature is set lower than the surface temperature of the metal rollers. The surface temperature of the slow-cooling roller is preferably set lower than the surface temperature of the metal rollers by 50° C. to 250° C. |
