Abstract: The present invention provides an actuator device comprising an actuator wire; a net-shaped electric heating element which covers a side surface of the actuator wire and comprises heating wires; and a controller for supplying electric power to the net-shaped electric heating element to heat the net-shaped electric heating element. The actuator wire is capable of being contracted by application of heat and restored by release of heat. The side surface of the actuator wire is formed of polymer. One end and the other end of the net-shaped electric heating element is connected to one end and the other end of the actuator wire, respectively. The net-shaped electric heating element is in contact with the side surface of the actuator wire, when the net-shaped electric heating element is not heated. The net-shaped electric heating element is moved outward from the side surface of the actuator wire due to contraction of the actuator wire, when the net-shaped electric heating element is heated.
