摘要： A pressure-sensitive adhesive article 100 includes a release sheet 1 constituted from a releasing agent layer 11 and a base material 12, and a pressure-sensitive adhesive sheet 2 constituted from a pressure-sensitive adhesive layer 21 and a pressure-sensitive adhesive sheet base 22. Such a pressure-sensitive adhesive article 100 has a structure in which the pressure-sensitive adhesive sheet 2 is laminated on the release sheet 1 so that the pressure-sensitive adhesive layer 21 is in contact with the releasing agent layer 11. The releasing agent layer 11 is composed of a material containing substantially no silicone compound. The releasing agent layer 11 is mainly composed of an elastomer and has a Young's modulus of 1.5 GPa or less. Preferred examples of the elastomer include polybutadiene rubber (especially, 1,4-polybutadiene rubber), polyisoprene rubber, and ethylene propylene rubber. The release sheet 1 has excellent releasability and has little adverse effect on electric components and the like.
