Abstract:
A liquid ejecting head includes a flow path substrate in which a nozzle through which liquid is ejected, a pressure chamber that communicates with the nozzle and a liquid supply chamber that communicates with the pressure chamber are formed, a vibration plate that is installed on the flow path substrate and overlaps with the pressure chamber and the liquid supply chamber, and a piezoelectric element that is formed on the vibration plate on an opposite side from the pressure chamber, in which a portion of the vibration plate overlapping with the pressure chamber is thinner in a thickness than a portion of the vibration plate overlapping with the liquid supply chamber.

Claim (Index 13):
A piezoelectric device that is provided in a liquid ejecting head that includes a flow path substrate in which a pressure chamber that communicates with a nozzle through which liquid is ejected and a liquid supply chamber that communicates with the pressure chamber are formed, the piezoelectric device comprising:\n a vibration plate that is installed on the flow path substrate and overlaps with the pressure chamber and the liquid supply chamber; and a piezoelectric element that is formed on the vibration plate on an opposite side from the pressure chamber, wherein a portion of the vibration plate overlapping with the pressure chamber is thinner in a thickness than a portion of the vibration plate overlapping with the liquid supply chamber.
