A surface-protective film comprising a substrate and a pressure-sensitive adhesive layer formed on one side thereof, wherein the pressure-sensitive adhesive layer is such that the difference between storage modulus at 150°C and that at 20°C satisfies a prescribed relationship and that the temperature at which the tan d is maximum is -5°C or below. The surface-protective film exerts excellent initial tackiness to the surface of an object to be protected, such as a metal sheet, a decorative laminated sheet, a plastic sheet, or a glass sheet, and exhibits little tack increase even after heat treatment, particularly even when used in a field accompanied with high-temperature heating. When the surface-protective film is peeled from an object protected therewith, the surface -protective film rarely leaves a pressure-sensitive adhesive residue on the surface of the resulting object. Further, the surface-protective film does not cause delamination phenomena such as lifting. |
