An ink-ejecting device includes an actuator plate formed of piezoelectric material having ferroelectric properties, and a base plate formed of conductive material. After both plates are joined, plural grooves and partition walls for separating the grooves from one another are formed. First electrodes for applying a driving voltage are formed at respective size surfaces of the first grooves so as to extend from open portions of the grooves to middle portions thereof. The first electrodes are individually and independently connected to a controller. Further, second electrodes are formed on entire inner surfaces of respective second grooves, and all the second electrodes are connected to the controller through the base plate. According to an alternative embodiment, the ink-ejecting device further includes an intermediate plate formed of insulation material. After the three plates are joined, plural grooves and partition walls for separating the grooves from one another are formed. First electrodes for applying a driving voltage are formed on entire inner surfaces of respective first grooves, and the first electrodes are individually and independently connected to a controller. Further, second electrodes are formed on entire inner surfaces of respective second grooves, and all the second electrodes are connected to the controller through the base plate. A method of manufacturing an ink-ejecting device also is described.
