    • PROBLEM TO BE SOLVED: To obtain a surface protective film that has excellent initial adhesive strength to an adherend, does not impair workability in peeling from an adherend, and, in application to a steel plate, prevents shocks to a steel plate during mechanical processing and a natural release from the steel plate during preservation. SOLUTION: The surface protective film is obtained by laminating an adhesive layer composed of an adhesive containing a rubber-based resin component (A) and a tackifier resin to a polyolefin-based substrate. The rubber-based resin component (A) is a mixture of a block copolymer (D) composed of a styrene-based polymer block (B) and an isobutylene-based polymer block (C) and a block copolymer (F) composed of a styrene-based polymer block (B) and a conjugated diene-based polymer block or a hydrogenated product (E) thereof.
