Abstract: According to an example, a base, a diaphragm, and a driving element are provided. The driving element includes a first electrode disposed on a second surface of the diaphragm, a second electrode opposing the first electrode, and a piezoelectric body interposed between the first electrode and the second electrode. In addition, an inter-wiring insulating film that covers the second surface of the diaphragm and the driving element, and an extracting electrode which is on the inter-wiring insulating film, are further provided. The inter-wiring insulating film includes a contact hole that exposes a part of the second electrode and through which the second electrode and the extracting electrode contact each other. The contact hole is disposed at a position which aligned with a solid portion of a circumferential wall of the pressure chamber in the base.

Abstract: An ink jet head comprises a substrate including a mounting surface and a pressure chamber open to the mounting surface. The ink jet head further comprises a nozzle plate including an inner surface fixed to the mounting surface and covering the pressure chamber, a nozzle open to the pressure chamber, and a piezoelectric element surrounding the nozzle and configured to deform to thereby change a volume of the pressure chamber. The ink jet head further comprises a deformation control unit disposed on and extending from the inner surface of the nozzle plate and surrounding the nozzle, the deformation control unit configured to cause deformation of the piezoelectric element to be substantially symmetric with respect to the nozzle.
