Liquid discharge head

Abstract

To provide a liquid discharge head that can be easily processed and can increase fluid resistance between a common liquid chamber and a pressure chamber.SOLUTION: A liquid discharge head according to an embodiment comprises an actuator and a nozzle plate. The actuator has a plurality of walls, where a plurality of grooves formed between the plurality of walls formed adjacently form a plurality of pressure chambers and a plurality of air chambers arranged alternately with the plurality of pressure chambers. A plurality of nozzles corresponding to the plurality of pressure chambers are formed in the nozzle plate. Throttle grooves whose widths are smaller than widths of the grooves are formed at least at the nozzle plate side, of the walls forming the pressure chambers.SELECTED DRAWING: Figure 2
