Provided is a surface protective sheet which satisfactorily adheres even to a coated surface having a rough surface, and not only does not cause an adhesive residue that can be observed with eyes but also does not impair the self-cleaning property of the surface of a coated plate. The surface protective sheet includes: a base material layer; and a pressure-sensitive adhesive layer, in which: the pressure-sensitive adhesive layer has an adhesion for a coated steel plate having a ten-point average surface roughness Rz of 8.0 μm of 0.05 N/20 mm or more; a main component in a pressure-sensitive adhesive for constructing the pressure-sensitive adhesive layer includes a polymer P obtained by cross-linking a polymer A; the polymer A has a weight-average molecular weight Mw of 500,000 or more; the polymer A has a distribution degree Mw/Mn of 8.0 or less; and an insoluble content of the polymer P in ethyl acetate is 90 wt % or more.
