Abstract:
A liquid discharge apparatus includes: a nozzle plate having a plurality of nozzles; a pressure chamber communicating with the nozzle; and a pressure generating element, in which each of the nozzles is formed by communicating a first opening portion and a second opening portion, when two nozzles adjacent to each other are represented by a first nozzle and a second nozzle, the second opening portion of the first nozzle and the second opening portion of the second nozzle are disposed along a first direction, each of the second opening portions extends in a second direction, and an inner diameter of the second opening portion in the second direction is larger than an inner diameter of the first opening portion, the first opening portion of the first nozzle and the first opening portion of the second nozzle are disposed so as to be shifted from each other in the second direction.
