PROBLEM TO BE SOLVED: To provide a roll film excellent in heat resistance and impact resistance and hard to generate a curling inclination even if it is preserved in a state wound around a core. SOLUTION: A roll film comprises a laminated film wherein thermoplastic polyester resin (A) layers are laminated on both surfaces on a cyclic olefinic resin (C) layer through adhesive (B) layers. The cyclic olefinic resin (C) is preferably composed of at least one resin selected from the group consisting of anα-olefin-cyclic olefin random copolymer [C-1] obtained from a 2-20Cα-olefin and a cyclic olefin having a specific structure, a ring opening polymer or copolymer of the cyclic olefin [C-2], a hydrogenated matter [C-3] of the polymer [C-2] and a graft modified matter of [C-1], [C-2] or [C-3].
