Abstract:
A liquid discharge head comprises a base member, a plurality of nozzles which discharge drops of a liquid, a plurality of liquid chambers which communicate with the plurality of nozzles respectively, and a plurality of piezoelectric elements generating a pressure to pressurize the liquid in each of the plurality of liquid chambers. In the liquid discharge head, a plurality of piezoelectric element members in which the plurality of piezoelectric elements are formed with grooves in columns by slot processing are arranged on the base member in rows along a direction of the columns of the plurality of piezoelectric elements.
