PROBLEM TO BE SOLVED: To provide a laminated film that has a metallic luster tone, has low saturation and fewer changes in saturation at the time of molding, and has less appearance defects.SOLUTION: A laminated film 1 has such a structure that 250 or more layers of layers (A layers) containing resins A and layers (B layers) containing resins B are alternately laminated in a thickness direction in total; has a layer (thick film layer) with a thickness of 1 μm or more and a layer (thin film layer) with a thickness of less than 1 μm; and satisfies the following (1) to (3): (1) any outermost surface layer is formed of the A layer and has a layer thickness of 5-10 μm, in both surfaces of the film; (2) the resin A is polyethylene terephthalate or polyethylene naphthalate, and the resin B is polyester containing spiroglycol, in a ratio of a spiroglycol residue in the total diol residue to the resin B of less than 12-18 mol%; and (3) unevenness of a lamination ratio in a film width direction of the A layer and the B layer in the thin film layer represented by formula 1 is 1% or less.SELECTED DRAWING: None |
