Patent ID: 8506057

Claim:
A liquid droplet ejecting head comprising: a pressure chamber substrate provided with a pressure chamber communicating with a nozzle orifice, wherein a plurality of the pressure chambers are arranged on the pressure chamber substrate in a first direction; an oscillating plate that has a first surface and a second surface opposed to the first surface, wherein the first surface covers the pressure chamber as viewed from a second direction which is orthogonal to the first direction and is a normal direction of the first surface; a plurality of first conductive layers formed, as viewed from the second direction, to cover the second surface of the oscillating plate within an area overlapping with the first area surface in the first direction, and to cover the second surface of the oscillating plate by extending up to the outside of the area overlapping with the first area surface on at least one side in a third direction orthogonal to the first direction and the second direction; a piezoelectric layer formed, as viewed from the second direction, to cover the first conductive layer in at least the area overlapping with the first area surface; and a second conductive layer continuously formed, as viewed from the second direction, to cover the piezoelectric layer in the first direction at least within the area overlapping with the first area surface, and being formed to cover at least a part of the piezoelectric layer while overlapping with a part of the plurality of first conductive layers in the third direction, and having, as viewed from the second direction, extending portions, which extend toward both sides in the third direction, in at least a part of an area between adjacent first conductive layers, wherein the extending portions are provided, as viewed from the second direction, at positions which do not overlap with the first area surface.
