An object of the present invention is to provide a pressure-sensitive adhesive composition which is excellent in antistatic property of a non-electrification-prevented adherend (subject to be protected) upon peeling, and has reduced stainability in an adherend and is excellent in adhesion reliance, and electrification preventing pressure-sensitive adhesive sheets using the same. There is provided a pressure-sensitive composition comprising an ionic liquid, and a (meth)acryl-based polymer containing, as a monomer component, 0.1 to 100% by weight of a (meth)acrylic acid alkylene oxide. In addition, there is provided a pressure-sensitive composition comprising an ionic liquid, and a polymer containing, as a monomer component, 0.5 to 30 % by weight of a nitrogen-containing monomer and having a glass transition temperature Tg of no higher than 0°C. Furthermore, there is provided a pressure-sensitive composition comprising an ionic liquid, and a (meth)acryl-based polymer containing, as a monomer component, 0.01 to 20% by weight of a reactive surfactant.
