Claim 0:
1. A joined body comprising an electrical debonding adhesive sheet, a first adherend, and a second adherend, wherein
the electrical debonding adhesive sheet comprises a substrate for voltage application comprising an electroconductive layer and a base layer, a first adhesive layer that 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 formed on the base layer of the substrate for voltage application,
the electrical debonding adhesive sheet has a protrudent part in which the second adhesive layer and the substrate for voltage application extend and protrude with respect to the first adhesive layer in a plane direction of the electrical debonding adhesive sheet,
the second adherend is adhered to the electrical debonding adhesive sheet by the second adhesive layer,
some of the electrical debonding adhesive sheet is folded back along an end of the second adherend so that some of the second adherend is sandwiched, and at least some of the protrudent part is adhered, by the second adhesive layer, to that surface of the second adherend which is on the reverse side from the first adherend, and
the first adherend is adhered to the electrical debonding adhesive sheet by a portion of the first adhesive layer which is not folded back.
