Patent ID: 8672459

Claim:
A liquid ejecting head comprising: a plurality of nozzles configured to eject liquid; a plurality of pressure generation chambers, each in fluid communication with one of the nozzles; a manifold substrate comprising a plurality of manifolds, each configured to supply liquid to at least one of the pressure generation chambers; a head case comprising a piezoelectric element housing unit; a plurality of piezoelectric elements configured to change pressure of liquid within the pressure generation chambers, disposed in the piezoelectric element housing unit; a vibrating element configured to absorb pressure changes in the liquid within the manifolds; a plurality of cavities provided on the vibrating element at positions that correspond to positions of the manifolds, the plurality of cavities including a first cavity and a second cavity, the piezoelectric element housing unit being between the first cavity and the second cavity; and an atmosphere exposure channel that provides fluid communication between the first cavity and the atmosphere; wherein at least the second cavity is in fluid communication with the atmosphere exposure channel via the first cavity.
