Abstract
An electrically peelable pressure sensitive adhesive sheet has a pressure sensitive adhesive layer formed of an electrically peelable pressure sensitive adhesive composition comprising an acrylic copolymer (A) comprising 1 to 99 mass % of a constituent unit (a1) derived from a compound represented by the following general formula (a1), and a surfactant (B). The electrically peelable pressure sensitive adhesive sheet has high adhesion before voltage application, but the adhesion can be effectively decreased by voltage application for a short time.
