    • The present invention provides an actuator which suppresses the inflow of water and the like, and is unlikely to cause cracking and peeling even when repeatedly driven. An actuator having a conductive layer and an ion-conducting layer includes: a first layer which is provided in contact with the actuator and is formed from a polymer that suppresses the permeation of water; and a second layer which is provided in contact with the first layer, has a lower tensile elastic modulus than that of the first layer, protects the first layer, and is formed from a polymer. The first layer and the second layer can cover the whole actuator.
    • 本发明提供一种抑制水等的流入的致动器,即使在重复驱动的情况下也不会引起开裂和剥离。 具有导电层和离子传导层的致动器包括:第一层,其设置成与致动器接触并由聚合物形成,该聚合物抑制水的渗透; 与第一层接触的第二层具有比第一层低的拉伸弹性模量,保护第一层,并由聚合物形成。 第一层和第二层可以覆盖整个致动器。
