PROBLEM TO BE SOLVED: To provide a laminated film which is excellent in thermal deformation resistance.SOLUTION: A laminated film includes at least two polyester films stuck on each other via an adhesive layer. At least one polyester film is a polyester film (layer I) constituted mainly of polyethylene terephthalate or polyethylene naphthalate, and at least one polyester film is a polyester film (layer II) including a structure in which a layer A constituted mainly of a polyester resin A composed of polyethylene terephthalate or polyethylene naphthalate and a polyester resin B composed of polyester with which cyclohexanedimethanol is copolymerized by 10-90 mol% as a diol component are laminated alternately by 800 layers or more, respectively, in the thickness direction. |
