Abstract

See full text

A liquid ejecting head includes a liquid discharge unit with a pressure generating chamber group which communicates with a nozzle disposed on a nozzle surface and is formed from pressure generating chambers disposed in a first direction, and a case member which communicates with the pressure generating chamber group and holds a liquid. The case member has a liquid inlet on the side opposite to the liquid discharge direction and at a position between the pressure generating chambers at both ends in the first direction. First and second liquid discharge units are arranged at positions where the first directions of the first and second liquid discharge units are parallel to each other in a second direction that is orthogonal to the first direction, and positions of the liquid inlets of the case member respectively corresponding to the first and second liquid discharge units do not overlap in the second direction.
