<P>PROBLEM TO BE SOLVED: To provide a surface protection film having good handling properties which is free of contamination such as a visually recognizable residual adhesive on the surface of an adherend after peeling the film, excels in blocking resistance without causing blocking to make a cake by adhering a base material layer to an adhesive layer, and is weak in interfacial adhesion between adhesive faces when the faces are made to adhere mutually, while having practical adhesion as a surface protection film, and the faces are particularly less in contamination such as whitening and surface roughness after peeling the mutually adhering portion thereof. Ž<P>SOLUTION: The film includes a base material layer (A) and an adhesive layer (B). The adhesive layer (B) includes a mixture of 10-50 mass% of a block copolymer having crystalline olefin blocks (B1), 10-50 mass% of a propylene polymer (B2) and 10-70 mass% of a linear low-density polyethylene with 0.880-0.938 g/cm<SP>3</SP>density (B3).
