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.
