PROBLEM TO BE SOLVED: To provide a novel surface protective film having substrate layer including a polyolefin resin, the surface protective film capable of exhibiting remarkably excellent peeling antistatic performance, exhibiting excellent inspectability at a very high level, and having an excellent unwinding property when unwinding from a wound body.SOLUTION: A surface protective film includes a substrate layer and an adhesive layer. The substrate layer includes polyolefin resin. The polyolefin resin is at least one kind selected from homopolypropylene and random polypropylene. Image sharpness is 50% or more in a MD direction with an optical comb of 0.125 mm wide. The surface specific resistance value of the adhesive layer is 1.0×10Ω/sq. or less.SELECTED DRAWING: Figure 1 |
