Abstract: Provided is a surface protective sheet, which satisfactorily adheres to an adherend and which can be easily re-released and suppresses contamination due to a pressure-sensitive adhesive remaining on the surface of the adherend after the release of the sheet. The surface protective sheet includes: a base material layer; and a pressure-sensitive adhesive layer, in which a difference ΔT (%) between the visible light transmittance T1 (%) of a transparent substrate having an antireflection film and the visible light transmittance T2 (%) of the transparent substrate resulting when the surface protective sheet is attached to one side of the transparent substrate and left to stand at 160° C. for 1 hour, and then the surface protective sheet is released under a temperature environment of 23° C. (ΔT=T1−T2) satisfies a relationship of ΔT≦1.8.

Abstract: The pressure-sensitive adhesive film according to the present invention comprises a resin film as a substrate and a pressure-sensitive adhesive layer provided at least on a face of the resin film. The resin film has a multi-layer constitution consisting of at least two layers. The resin film has a laser beam reflectance of 5% or higher, but 40% or lower in a wavelength range of 1000 nm to 1100 nm, and has a laser beam transmittance of 5% or lower in the said wavelength range.
