There is provided a method of manufacturing a piezoelectric actuator, which has high production efficiency and is available to miniaturize the piezoelectric actuator. Also, piezoelectric actuators are packed simply and a quality examination before shipment is performed easily. In this manufacturing method, various part sheets except for piezoelectric bodies of the piezoelectric actuators are joined to a piezoelectric material sheet having a size that a plurality of piezoelectric actuators can be formed, so as to from the plurality of piezoelectric actuators, and the piezoelectric material sheet is formed with a predetermined poling structure. Then, the piezoelectric material sheet is divided to manufacture the plurality of piezoelectric actuators. Also, dividing of the piezoelectric material sheet may be performed in a place where the piezoelectric actuator is to be used. <IMAGE> |
