Patent ID: 8157366

Claim:
A liquid ejecting head, comprising: a plurality of parallelly-arranged pressure generating chambers each discharging a liquid through a nozzle orifice by pressure fluctuation; a plurality of pressure generating elements which each generate a pressure fluctuation in the corresponding pressure generating chamber; a reservoir provided along a direction in which the plurality of pressure generating chambers are parallelly-arranged for supplying a liquid to the pressure generating chambers, the reservoir including a first area and a second area of a width smaller than that of the first area in a direction perpendicular to the direction in which the pressure generating chambers are parallelly-arranged; and a compliance member provided in an area corresponding to the reservoir for absorbing pressure fluctuation in the reservoir, wherein: the compliance member includes a first compliance section formed at the upper surface side of the reservoir and a second compliance section formed at the lower surface side of the reservoir, wherein the first compliance section is part of a liquid supply port-forming substrate and has a smaller width than the other portions of the liquid supply port-forming substrate; and the first compliance section is formed at an area corresponding to both the first area and the second area of the reservoir, and the second compliance section is not formed in at least an area corresponding to a part of the first area.
