<p>Disclosed is a surface protection film which has excellent initial adhesive force and can be easily removed from an object to which it is adhered. The adhesive force of this surface protection film does not undesirably increase as time passes. Specifically disclosed is a surface protection film wherein a rubber adhesive layer containing a rubber resin is arranged on a polyolefin substrate. The rubber resin is composed of a styrene elastomer which has a block copolymer of a styrene polymer block (A) and an olefin elastomer component (B), a block copolymer of a styrene polymer block (A) and a random copolymer block (B') of styrene and an olefin, or a hydrogenated product of either of the block copolymers as a main component. The rubber adhesive layer has a tensile storage modulus at a frequency of 10 Hz of not less than 2.5 × 10 9 Pa at -100 °C, and a shear storage modulus at a frequency of 10 Hz of from 5 × 10 4 to 5 × 10 6 Pa at 23 °C.</p>
