Abstract

A liquid ejecting head includes: a nozzle plate including a first-nozzle; first and second pressure chambers arranged side by side in a first-direction; third and fourth pressure chambers arranged side by side in the first-direction; a first-communication-flow-path extending along the nozzle plate, coupled to the first-nozzle, and communicating with the first to fourth pressure chambers; a first-common-liquid-chamber communicating with the first and second pressure chambers; and a second-common-liquid-chamber communicating with the third and fourth pressure chambers. The first and second pressure chambers and the third and fourth pressure chambers are shifted in a second-direction orthogonal to the first-direction. When a width of the first communication flow path in the first-direction at a position overlapping the first-nozzle is defined as a first-width, and a width of the first-pressure-chamber in the first-direction is defined as a pressure chamber width, the first-width is equal to or greater than the pressure chamber width.
