Zusammenfassung:To provide a method for bonding and separating adherends in which adherends can easily be separated by application of voltage of a low voltage (less than 20 V).SOLUTION: The method for bonding and separating adherends is a method for bonding an adhesive sheet X1 at least comprising the electrolyte-containing adhesive layer 11 to adherends and thereafter applying a voltage of less than 20 V to the adhesive layer so as to generate a potential difference in the thickness direction of the adhesive layer, to separate adherends. The electrolyte-containing adhesive layer preferably has a thickness of 1 μm or more and 1000 μm or less, the applying time of the voltage preferably is within 60 seconds, and the electrolyte preferably is an ionic liquid.SELECTED DRAWING: Figure 1 【課題】低い電圧(20V未満)の電圧印加により、容易に被着体を分離できる被着体の接合・分離方法を提供する。【解決手段】被着体の接合・分離方法は、電解質を含有する粘着剤層11を少なくとも含む粘着シートX1を被着体と接合した後、前記粘着剤層の厚さ方向に電位差を生じるように前記粘着剤層に20V未満の電圧を印加し、被着体を分離する方法である。前記電解質を含有する粘着剤層は、1μm以上1000μm以下の厚さを有することが好ましく、前記電圧の印加時間は60秒以内であることが好ましく、前記電解質はイオン液体であることが好ましい。【選択図】図1
