Abstract: A laminated film in which a heat-resistant base film and a metal foil are bonded using an adhesive is provided with a barrier layer that prevents chemicals from entering the adhesive layer, between the metal foil and the adhesive layer. The barrier layer is made of a heat-resistant resin similar to that of the base film and has a water absorption rate of 1% or less. The adhesive layer is a silicone-based resin and has a thickness of 40 μm or more after drying.
