1. An electrical debonding adhesive sheet comprising a substrate for voltage application, which comprises an electroconductive layer and a base layer, a first adhesive layer, which is constituted of an electrically debondable adhesive and is formed on the electroconductive layer of the substrate for voltage application, and a second adhesive layer, which is formed on the base layer of the substrate for voltage application,
the electrical debonding adhesive sheet having: a first protrudent part, in which the first adhesive layer and the substrate for voltage application extend and protrude with respect to the second adhesive layer in a plane direction of the electrical debonding adhesive sheet; and a second protrudent part, in which the substrate for voltage application extends from the first protrudent part and protrudes with respect to the first adhesive layer in a plane direction of the electrical debonding adhesive sheet.
