| description | A liquid ejecting head includes a flow channel forming substrate that is provided with a space constituting a pressure generating chamber which communicates with nozzle openings, a vibration plate that is stacked on one surface of the flow channel forming substrate and seals the space, and a piezoelectric element that includes a first electrode, a piezoelectric layer, and a second electrode sequentially stacked on a surface of the vibration plate opposite to the flow channel forming substrate, in which the first electrode is formed, in which at least a width of a first direction along the opposite surface is narrower than the space in a region corresponding to the space, the piezoelectric layer is stacked so as to overlap the first electrode and at least a part of the vibration plate in the region corresponding to the space, the second electrode is stacked so as to overlap the piezoelectric layer in the region corresponding to the space, and as a thickness of a stacked direction of the piezoelectric element is a thickness of the piezoelectric layer, a first thickness (D1) of the piezoelectric layer of a part positioned on the first electrode and a second thickness (D2) of the piezoelectric layer of a part positioned on the vibration plate satisfy a relationship of the first thickness (D1)>the second thickness (D2). |
