Surface protective film, optical components and electronic components

Abstract

The objective of this invention is to provide a surface protective film that exhibits excellent light peelability and suppresses the increase of peel force over time. Furthermore, the objective of this invention is to provide an optical component and an electronic component incorporating such a surface protective film. An embodiment of the present invention provides a surface protective film comprising a substrate and an adhesive layer comprising a carbamate-based adhesive. The ratio (Svr / Smr) of the area ratio of valleys to the area ratio of hills on the surface of the adhesive layer, measured using a scanning white interference microscope, is 1.0 or higher.
