Patent ID: 8104883

Claim:
A liquid ejecting head comprising: a plurality of pressure generating chambers that are communicated with corresponding one of nozzle orifices that eject liquid, the plurality of pressure generating chambers being arranged in parallel; a first substrate having a reservoir unit constituting at least a part of a reservoir that is a common liquid chamber that supplies the liquid to the plurality of pressure generating chambers; and a second substrate having a compliance unit that absorbs pressure change, the second substrate being combined with one surface of the first substrate via an adhesive layer, wherein the reservoir unit is provided over the pressure generating chambers in an arrangement direction of the pressure generating chambers, and the reservoir unit has a first area and a second area whose width in a direction perpendicular to the arrangement direction of the pressure generating chambers is smaller than a width of the first area, the compliance unit is provided to seal the reservoir unit and the surrounding of the compliance unit is fixed by the adhesive layer, and a width of the compliance unit corresponding to the second area of the reservoir unit is formed so as to be larger than the width of the second area, wherein a distance between an end face of the reservoir unit and the adhesive layer in the second area becomes larger as the width of the reservoir unit becomes smaller.
