PROBLEM TO BE SOLVED: To obtain an actuator wherein constitution is simple and manufacturing is easy, by bending both members by using one ends of two members constituted of electromechanical transducing elements which are partly polarized in arbitrary directions, as a fixed fulcrum, and swinging the other ends of both of the members. SOLUTION: After two sheets of electromechanical transducing elements, e.g. piezoelectric boards 21, 22 are stuck sandwiching an intermediate electrode 23, and electrodes are formed on both of the whole surfaces, surface electrodes 24a, 24b, 25a, 25b which are divided into two parts are formed. A bimorph wherein the surface electrodes 24a, 24b, 25a, 25b are formed is polarized in parallel, and the electrodes 24a and 24b, and 25a and 25b are electrically connected. Thereby the actuator is constituted of a driving part of cantilever structure wherein an end part of the parallel polarized bimorph 201 is fixed, and a driving circuit wherein the respective terminals of an AC power supply 34 are connected with the surface electrodes 24a and 24b, and 25a and 25b of the parallel polarized bimorph 201. |
