A surface-protective film affixed to an optical member or an electronic member and used for protecting a surface thereof, wherein the surface-protective film is provided with a substrate including a polyethylene terephthalate film, an adhesive layer provided on one side of the substrate, and a release film provided on the adhesive layer, and the surface-protective film satisfies (A) through (D). (A): The bending resistance of the substrate is 5000-85000 mN∙cm. (B): The elastic modulus of the adhesive layer is 1.0×104 to 1.0×107 Pa. (C): The thickness of the release film is at least 20 µm. (D): The ratio of the bending resistance of the substrate and the bending resistance of the release film [Substrate bending resistance/Release film bending resistance] is 1.0 to 4.0. The surface-protective film has excellent working efficiency during affixing and release, and minimal burden on an adherend during releasing therefrom. |
