Abstract:
A liquid ejecting head includes a plurality of nozzle groups each including a plurality of nozzle openings; and a plurality of pressure generating chambers that cause liquid to be ejected from the nozzle openings. A plurality of recessed portions are formed at a nozzle forming member, the recessed portions each having a thickness smaller than a thickness of the nozzle forming member, the nozzle openings being formed at the recessed portions. A set of at least one of the plurality of nozzle openings included in each single nozzle group defines a nozzle set, the nozzle set being arranged to correspond to each of the pressure generating chambers. The nozzle groups each have a plurality of nozzle sets in an array, the nozzle sets of one of the nozzle groups being relatively shifted from the nozzle sets of another one of the nozzle groups in a nozzle-set-array direction.
