To provide an adhesive layer that has excellent heat resistance and allows its adhesion to sufficiently decrease with application of voltage.SOLUTION: The present invention pertains to an adhesive composition comprising a polymer and an ionic liquid, wherein, when an adhesive layer formed of the adhesive composition is attached to an adherend, and peeled off after applying a voltage of 10 V for 10 seconds, the amount of the ionic liquid exuded is at least 0.002 mg/cm2.SELECTED DRAWING: Figure 1 【課題】耐熱性に優れ、電圧の印加により十分に接着力が低下する粘着剤層を提供する。【解決手段】ポリマーとイオン液体とを含む粘着剤組成物であって、前記粘着剤組成物により形成した粘着剤層を、被着体に貼付し、１０Ｖの電圧を１０ｓｅｃ印加後剥離した際の、イオン液体の染み出し量が０．００２ｍｇ/ｃｍ２以上である粘着剤組成物。【選択図】図１
