Abstract
Official abstract text for this publication.
A liquid ejecting head includes a plurality of pressure generators each including a first electrode individually provided therefor, the first electrode being located on a face of the flow path plate so as to correspond to one of the pressure chambers, a piezoelectric layer provided on the first electrode, and a second electrode provided on the piezoelectric layer; a lead electrode electrically connected to the first electrode; and a conductive layer provided in a section where the first electrode is partially exposed, the section being located in a region where the second electrode is not provided and the piezoelectric layer is exposed, at least a part of the conductive layer being in contact with the first electrode. The lead electrode is connected to the first electrode via the conductive layer.
First claim
Opening claim text (preview).
What is claimed is: 1. A liquid ejecting head comprising: a flow path plate having a first surface and a second surface opposite to the first surface, the flow path plate including a plurality of pressure generators; each of the plurality of pressure generators comprises: a pressure chamber that is provided in the flow path plate and that communicates with a nozzle that ejects a liquid; a first electrode that is formed over the first surface of the flow path plate and the pre…
