Abstract
A liquid ejecting head includes: a nozzle; first to fourth pressure chambers; a communication flow path coupled to the nozzle and communicating between the nozzle and the first to fourth pressure chambers; first to fourth flow paths coupling the communication flow path and the first to fourth pressure chambers; a first-common-liquid-chamber communicating with the first-pressure-chamber and the second-pressure-chamber; and a second-common-liquid-chamber communicating with the third-pressure-chamber and the fourth-pressure-chamber. The first-flow-path and the second-flow-path are arranged side by side in a first-direction, the third-flow-path and the fourth-flow-path are arranged side by side in the first-direction, and the first-flow-path and the second-flow-path, and the third-flow-path and the fourth-flow-path are arranged to be shifted in a second-direction orthogonal to the first-direction. The first-flow-path is shifted from each of the third-flow-path and the fourth-flow-path in the first-direction, and the second-flow-path is shifted from each of the third-flow-path and the fourth-flow-path in the first-direction.
