Abstract
This invention provides a polymer actuator having a structure such that voltage can be efficiently applied to two or more actuator electrodes without directly providing an electrical contact point to an expanding and contracting portion. An actuator has: an insulating base material; a first terminalfor energizing provided contacting the insulating base material; a first actuator electrodeprovided contacting the first terminal; an electrolyte layerprovided contacting the first actuator electrode; a second actuator electrodeprovided contacting the electrolyte layer; a second terminalfor energizing provided spaced apart from the first terminal and contacting the insulating base material; an energization preventing portionfor preventing energization of the first terminal and the second terminal; and a connecting portionprovided contacting the energization preventing portion in order to energize the second actuator electrode and the second terminal.
