Patent ID: 7804225

Claim:
A droplet discharging head comprising: a diaphragm; a fixing plate; and a piezoelectric element, the diaphragm including a first part and a second part, the first part having a first thickness, the second part having a second thickness, the first thickness being less than the second thickness, the piezoelectric element including a first electrode, a second electrode, a piezoelectric body that is interposed between the first electrode and the second electrode, a first internal electrode extending from the first electrode, a second internal electrode extending from the second electrode, the diaphragm, the piezoelectric element, and the fixing plate being arranged toward a first direction in this order, when looking from the first direction, one of the first electrode and the second electrode is disposed above the first part of the diaphragm with the first thickness, with the other of the first electrode and the second electrode being disposed above the second part of the diaphragm with the second thickness.
