Abstract:
1. A droplet ejecting apparatus, comprising: a droplet ejecting head including a cavity unit in which a plurality of pressure chambers are arranged in a plurality of rows and a piezoelectric actuator which is superposed on the cavity unit and which permits a liquid in the pressure chambers to be ejected therefrom as a droplet; a voltage application device configured to apply a voltage to the piezoelectric actuator; wherein the piezoelectric actuator includes: wherein the connection portion of each of the plurality of individual electrodes is disposed so as to overlap the second trunk portion of the second potential electrode as seen in a superposition direction in which the cavity unit and the actuator are superposed; wherein the plurality of individual electrodes are arranged in a plurality of rows so as to correspond to the plurality of rows of the plurality of pressure chambers, and all of the connecting portions of the respective individual electrodes that belong to any one of the plurality of rows are disposed on the same side with respect to the pressure chambers that correspond to the respective individual electrodes, in a direction in which the plurality of rows are arranged; and wherein the connecting portions of the respective individual electrodes that belong to one of any adjacent two of the plurality of rows and the connecting portions of the respective individual electrodes that belong to the other of said any adjacent two of the plurality of rows are disposed on mutually opposite sides with respect to the pressure chambers to which the respective individual electrodes that belong to the one and the other of said any adjacent two of the plurality of rows respectively correspond.
