Patent ID: 7585062

Claim:
A liquid ejecting head, comprising: a passage unit, having a nozzle opening, a pressure generating chamber communicating with the nozzle opening, a reservoir holding a liquid to be supplying to the pressure generating chamber, and a vibrating plate closing openings of the pressure generating chamber and the reservoir; a head case, on which the passage unit is attached; and a pressure generating element for applying variance of pressure to the pressure generating chambers, accommodated in a space defined in the head case, wherein an air sealing member contacts a surface of the head case and a surface of the pressure generating element to seal a gap between the head case and the pressure generating element so that a sealed space portion surrounded by the vibrating plate, the head case and the pressure generating element is formed, and wherein, when the liquid in the reservoir is vaporized, the vaporized liquid is passable through the vibrating plate.
