PROBLEM TO BE SOLVED: To enable quick big deformation, unfrequent wrong operations and high speed actuation in the actuation element or actuator of very simple structure using a shape memory alloy. SOLUTION: Two panel point members 4, 5 are arranged on the positions separated from each other and connected by drive members 2, 3 consisting of two shape memory alloy. A heating means is provided by which the drive members 2, 3 can be heated individually and separately to the temperature (martensite transformation start temperature) or more in which the restoring force to the shapes 6, 7 memorized in these drive members is exerted. Each of drive members 2, 3 is different in the memorized shape, namely the restored shape at the deformation time to austenite phase. Such actuation element can be connected plural to a straight line direction, plane direction or solid direction and constitute the actuator by which each can be driven independently.
