Patent ID: 8047635

Claim:
A liquid ejecting head comprising: a channel forming substrate in which a plurality of pressure generating chambers which communicate with nozzle orifices which eject liquid are arranged in a single direction; a reservoir forming substrate provided with a reservoir serving as a common liquid chamber which communicates with the plurality of pressure generating chambers in a manner such that the reservoir is disposed over a way across the plurality of pressure generating chambers; and a pressure generating unit which causes pressure change to the plurality of pressure generating chambers, wherein at least a portion of a wall surface of the reservoir is an inclined surface, a lower side of the reservoir in a vertical direction is provided with a lower portion of which a width is wider than an upper portion of the reservoir in the vertical direction thanks to the inclined surface, a compliance portion which absorbs pressure of the reservoir is disposed at an area which faces the lower portion and has a shape corresponding to the lower portion, and the reservoir communicates with an upper portion of each of the pressure generating chambers in the vertical direction rather than a lower portion of each of pressure generating chambers.
