An object of the present invention is to provide a pressure-sensitive adhesive composition which is excellent in antistatic property of a pressure-sensitive adhesive tapes when separators are peeled off, and has reduced stainability in an adherend, and excellent in transparency, and prevention of occurrence of peeling off and separation, and an antistatic pressure-sensitive adhesive sheet and a double-sided pressure-sensitive adhesive tape using the same. There is provided a pressure-sensitive composition comprising an ionic liquid, a (meth)acryl-based oligomer of weight-average molecular weight of 1,000 to 50,000, and a (meth)acryl-based polymer of glass transition temperature (Tg) of 0°C or less as base polymer.
