Patent ID: 8360558

Claim:
A liquid droplet discharging head comprising: a pressure chamber substrate in which a pressure chamber that is in communication with a nozzle hole is formed, the pressure chamber being formed in the pressure chamber substrate as a plurality of compartments adjacent to one another in a first direction; a vibrating plate that has a first surface for covering the pressure chamber and a second surface as an opposite surface, the vibrating plate having a first area surface as a part of the first surface, the first area surface covering the pressure chamber in a view in a second direction that is orthogonal to the first direction and is normal to the first surface; a first conductive layer that is formed at a plurality of areas to cover, in a view in the second direction, the second surface of the vibrating plate inside each area that overlaps the first area surface in the first direction and, in a view in the second direction, extends from the area overlapping the first area surface to an area that is located outside the area overlapping the first area surface at least one side in a third direction to cover the second surface thereat, the third direction being orthogonal to both the first direction and the second direction, wherein at least a portion of the first conductive layer contacts at least a portion of the vibrating plate; a piezoelectric substance layer that covers the first conductive layer at least inside the area overlapping the first area surface in a view in the second direction; and a second conductive layer that covers, in a view in the second direction, at least a part of the piezoelectric substance layer in such a manner that the second conductive layer lies over the first conductive layer in the first direction and lies over a part of the first conductive layer in the third direction at least inside the area overlapping the first area surface, the second conductive layer lying over the first conductive layer formed at the plurality of areas in a view in the second direction, wherein at least one of the first conductive layer, the second conductive layer, and the piezoelectric substance layer covers the vibrating plate in a view in the second direction, and wherein at least a portion of the second conductive layer contacts at least a portion of the vibrating plate.
