PROBLEM TO BE SOLVED: To simplify assemblage, and reduce load in action by reducing electric wiring in an actuator. SOLUTION: A movable part 10 formed of conductive material is contained inside a support body 20, and shape memory alloy members 30a, 30b are provided inside the support body 20 as drive mechanisms. The shape memory alloy members 30a, 30b are respectively formed as coil springs, and one end side of each is connected to a separately provided electrode terminal 41a, 41b, while the other side is connected to a fixed part 11a, 11b of the movable part 10. On a lower end part of the movable part 10, an electrode terminal 42 is provided, and the electrode terminal 42 is set continuous with the fixed parts 11a, 11b by the movable part 10. By wiring one lead wire to the electrode terminal 42, the fixed parts 11a, 11b are kept at a common potential.
