摘要:
A liquid discharging head includes a piezoelectric actuator including a plurality of piezoelectric elements and a plurality of electric supply members. The plurality of piezoelectric elements is provided in a row and includes an even number of piezoelectric element columns provided via a groove at a predetermined pitch. The plurality of electric supply members supplies electricity to the plurality of piezoelectric elements and includes electrodes disposed for the alternate piezoelectric element columns of the respective piezoelectric elements. One end of the electric supply member is positioned outwardly from an outer end of an endmost driven piezoelectric element column to which the electrode is connected, while another end of the electric supply member is positioned inwardly from an outer end of an endmost non-driven piezoelectric element column to which the electrode is not connected, in a manner that adjacent electric supply members do not overlap.
