Abstract
A release sheet is provided. The release sheet comprises: a base material having one surface and the other surface; and a release agent layer provided on the one surface of the base material. The release agent layer contains substantially no silicone compound and is constituted of a polymer material containing a polyolefine-based thermoplastic elastomer of which density is in the range of 0.80 to 0.90 g/cm. A Young's modulus of the release agent layer is in the range of 0.1 to 0.3 GPa. An arithmetic mean deviation of a profile Ra of the other surface of the base material is in the range of 100 to 1800 nm. This makes it possible to sufficiently suppress adverse effects on electric components and the like, prevent blocking from occurring when the release film is wound up in a rolled form and stored in this state, and exhibit superior releasability. A pressure-sensitive adhesive article is also provided.
