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 4):
The liquid ejecting head according to  claim 3 ,\n wherein a surface of the portion of the vibration plate overlapping with the liquid supply chamber on a side of the liquid supply chamber is formed of a compressive stress film, and the compressive stress film is not formed on the surface of the portion of the vibration plate overlapping with the pressure chamber on the side of the pressure chamber.
