PROBLEM TO BE SOLVED: To provide a surface protective film capable of achieving good conformability to a rugged level difference of an adherend and easy releasability in a good balance.SOLUTION: The surface protective film has a base material layer and a pressure sensitive adhesive layer formed on at least one surface of the base material layer. In the surface protective film: the tensile strength at 10% elongation is 14 N/20 mm or lower at 23°C; the adhesive force in peeling, as measured at 30 minutes after application to an SUS430BA plate and at 23°C, a pulling speed of 0.3 m/min, and a peel angle of 180°, is 1.0 N/20 mm or higher; and the adhesive force in peeling, as measured at 30 minutes after application to an SUS430BA plate and at 23°C, a pulling speed of 10 m/min, and a peel angle of 180°, is 4.0 N/20 mm or lower. |
