Zusammenfassung:	To provide a joint/separation method for an adherend capable of easily separate an adherend by applying low voltage (lower than 20 V).SOLUTION: A joint/separation method for an adherend includes: after jointing, with an adherend, a pressure sensitive adhesive sheet including at least an adhesive layer containing an electrolyte, applying voltage of less than 20 V to the adhesive layer so that electric potential difference is caused in a thickness direction of the adhesive layer; and then separating the adherend. The adhesive layer containing the electrolyte is preferably 1-1000 μm thick. The application of the voltage is preferably within 60 seconds. The electrolyte is preferably 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】本発明の被着体の接合・分離方法は、電解質を含有する粘着剤層を少なくとも含む粘着シート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
