发明名称 LIQUID EJECTING HEAD AND LIQUID EJECTING APPARATUS
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.

主权项 1. A liquid ejecting head comprising: a flow path plate including a plurality of pressure chambers communicating with a nozzle that ejects a liquid; a plurality of pressure generators each including a first electrode provided above the flow path plate, 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, wherein the first electrode is individually provided for each of the plurality of pressure chambers, the second electrode constitutes a common electrode for the plurality of pressure generators, and the lead electrode is connected to the first electrode via the conductive layer, and an opening is formed between the plurality of pressure generators by removing the second electrode and the piezoelectric layer.
