Liquid ejecting head, liquid ejecting apparatus, and piezoelectric device
Provided is a liquid ejecting head including a pressure chamber to accommodate a liquid, a vibration plate, a nozzle to eject the liquid, and a piezoelectric element. The piezoelectric element includes a piezoelectric body layer, a first electrode disposed on one surface of the piezoelectric body layer, and a second electrode disposed on the other surface of the piezoelectric body layer. The liquid ejecting head further includes wiring connected to the second electrode and extended along a surface direction of the piezoelectric body layer, and does not include a metal layer having the same potential as the first electrode in a first area which is an area positioned between the wiring and the vibration plate and in which the wiring overlaps with none of the second electrode and the piezoelectric body layer in a direction perpendicular to a surface direction of the second electrode.
