摘要:
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.
