PROBLEM TO BE SOLVED: To provide a laminated film with excellent environmental adaptability, heat resistance and releasing properties and at the same time, with excellent mechanical physical properties such as toughness. SOLUTION: In the laminated film in which a layer A and a layer C are the surface layers and a layer B exists between both layers, each layer is constituted of each of the below described composition. The layer A comprises 90-100 mass % styrene polymer with syndiotactic structure and 0-10 mass % other thermoplastic resin, etc. The layer B comprises 30-90 mass % styrene polymer and 10-70 mass % other thermoplastic resin, etc. The layer C comprises 70-100 mass % styrene polymer with syndiotactic structure and 0-30 mass % other thermoplastic resin, etc.
