PROBLEM TO BE SOLVED: To provide an optical unit which reduces the electric power consumption of the time when optical elements are displaced in order to perform focusing, zooming, deflection prevention, etc., and makes the response speed up in an optical device. SOLUTION: This optical unit is constituted by using a leaf spring actuator equipped with substrates 10 and 11 having at least one stationary electrodes and a substrate 12 having at least one movable leaf spring-like electrodes. The central portions of the substrates 10, 11 and 12 are respectively provided with holes 16, 17 and 18 and at least one holes are mounted with lenses, mirrors, prisms, etc. When a voltage is impressed between the substrate 11 and the substrate 12, an optical element supporting section 14 moves to the substrate 11 side and when the voltage is impressed between the substrate 10 and the substrate 12, the optical element supporting section 14 moves to the substrate 10 side. |
