Beschreibung
Zusammenfassung:	The present invention relates to a separation method for an adherend including: a first voltage application step of applying a voltage to an electrolyte-containing adhesive layer to change an adhesive force so as to generate a potential difference in a thickness direction of the electrolyte-containing adhesive layer in a state where the electrolyte-containing adhesive layer in an adhesive sheet containing at least the electrolyte-containing adhesive layer is allowed to bond to an adherend; a bonding maintenance step of recovering the adhesive force by allowing a predetermined time to elapse in the state where the electrolyte-containing adhesive layer is allowed to bond to the adherend, after the first voltage application step; a second voltage application step of applying a voltage to the electrolyte-containing adhesive layer to change the adhesive force so as to generate a potential difference in the thickness direction of the electrolyte-containing adhesive layer in the state where the electrolyte-containing adhesive layer is allowed to bond to the adherend, after the bonding maintenance step; and a separation step of separating the electrolyte-containing adhesive layer and the adherend.
