Electrically peelable adhesive composition, adhesive sheet, and joined body

A joined body having a laminate structure, comprising:

• a conductive adherend;
• and
• an adhesive sheet comprising:
• an adhesive layer that is formed of an electrically peelable adhesive composition;
• and
• a conduction substrate comprising a substrate and a conductive layer,
• wherein the electrically peelable adhesive composition comprises:
• a polymer dissolved in an organic solvent;
• the organic solvent;
• and
• an ionic liquid, and
• wherein an anion of the ionic liquid is a bis(fluorosulfonyl)imide anion.

A double-sided adhesive sheet, comprising:

• an adhesive sheet comprising:
• an adhesive layer that is formed of an electrically peelable adhesive composition;
• and
• a conduction substrate comprising a substrate and a conductive layer;
• and
• a further adhesive layer,
• wherein the electrically peelable adhesive composition comprises:
• a polymer dissolved in an organic solvent;
• the organic solvent;
• and
• an ionic liquid,
• wherein an anion of the ionic liquid is a bis(fluorosulfonyl)imide anion, and
• wherein the conduction substrate is sandwiched between the adhesive layer and the further adhesive layer.
