Abstract
There are provided a drive device and the like that are capable of suppressing characteristic degradation according to ambient environment. The drive device includes one or a plurality of polymer actuator devices each configured using an ion-exchange resin, and the ion-exchange resin contains operating ions that have activation energy equal to or smaller than a predetermined threshold. Degradation in ion conductivity in the ion-exchange resin is suppressed even in environment with low humidity, high temperature, and the like.
