PROBLEM TO BE SOLVED: To provide an actuator which can control, when built into an electronic device, stress at a supporting area. SOLUTION: A flexure displacement type actuator comprises a plate type piezoelectric element 1 including surface electrodes 2, 3, 4, and 5 and a rear surface electrode 6, and a supporting means provided in an area including a node of the piezoelectric element 1. The piezoelectric element 1 results in different displacement directions at both ends provided opposed with each other. |
