PROBLEM TO BE SOLVED: To provide a laminated film which is excellent in heat resistance, impact resistance, water vapor barrier property and easy tear-opening property and can be manufactured at low cost. SOLUTION: A thermoplastic polyester resin (A) layer and a cyclic olefin resin (C) layer are laminated via an adhesive (B) layer, and the above (A) layer and / or (B) layer is composed of two layers. The thickness of the thermoplastic polyester resin (A) layer (total) is 0.5 to 50 μm, the thickness of the adhesive (B) layer (total) is 0.5 to 20 μm, The thickness (total) of the olefin resin (C) layer is 5 to 15 A laminated film having a thickness of 0 μm. |
