Provided is a surface protective film capable of achieving both good followability to uneven unevenness of an adherend and light releasability in a well-balanced manner. The surface protective film of the present invention is a surface protective film having a base material layer and an adhesive layer on at least one side of the base material layer, and has a tensile strength at 10% tension of 14 N at 23 ° C. / 20 mm or less, and the peel adhesion to the SUS430BA plate is 1.0 N / 20 mm or more after 23 minutes at a temperature of 23 ° C., a tensile speed of 0.3 m / min, a peeling angle of 180 °, and SUS430BA. The peel adhesion to the plate is 4.0 N / 20 mm or less at 23 ° C., a tensile speed of 10 m / min, a peeling angle of 180 °, and 30 minutes after being stuck. [Selection] Figure 1 |
