PROBLEM TO BE SOLVED: To provide a pressure-sensitive adhesive composition which is excellent in removability, peel adhesive power temporal stability and staining properties, a pressure-sensitive adhesive layer and a pressure-sensitive adhesive sheet, and to provides a pressure-sensitive adhesive composition which can prevent electrification of a non-antistatic protected adherend when peeled off using an ionic compound which is an antistatic agent, and is less likely to cause lifting and is also excellent in removability, a pressure-sensitive adhesive layer produced with the same, and a pressure-sensitive adhesive sheet.SOLUTION: A pressure-sensitive composition includes a (meth)acryl-based polymer containing, as a main component, a (meth)acryl-based monomer having an alkyl group of 1 to 14 carbon atoms, an ionic compound, and an organopolysiloxane having an oxyalkylene chain, wherein the organopolysiloxane is represented by formula (1). In the formula, Rand/or Rmay have a 1-6C oxyalkylene chain and the end of the oxyalkylene chain may be an alkoxy group or a hydroxyl group, and n is an integer of 1 to 300. |
