摘要： 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.
