<p>An actuator includes an electrolytic layer, a first electrode layer, and a second electrode layer. The electrolytic layer includes a polymer and an ionic liquid included in the polymer. When a voltage that makes the first electrode layer a positive side is applied, the actuator deforms to be in a drive state, thereby driving a protruding member. In a period other than a drive period in which the protruding member is driven, a reverse voltage that makes the first electrode layer a negative side is applied, thereby rectifying the tendency of the actuator to bow or the like.</p> |
