Abstract:
A liquid ejecting head includes: a nozzle plate in which a first nozzle row of nozzle openings aligned along a first direction X and a second nozzle row of nozzle openings aligned along the X direction are disposed side by side along a second direction Y, perpendicular to the X direction; and a channel member including pressure generating chambers aligned along the X direction and nozzle communication holes that allow the pressure generating chambers and the nozzle openings to communicate with each other. The nozzle communication holes include first openings communicating with the pressure generating chambers and second openings open to the nozzle plate. The second openings have a width in the X direction larger than a width of the pressure generating chambers, alternatively communicate with the first nozzle row and the second nozzle row, and are alternatively arranged on different sides when viewed in the Y direction.
