Abstract:
There is provided a liquid ejecting head including: a flow path forming substrate in which a plurality of pressure generation chambers are arranged in parallel in a first direction; and a piezoelectric actuator which has a first electrode provided on one surface side of the flow path forming substrate with a vibration plate interposed therebetween, a piezoelectric layer provided on the first electrode, and a second electrode provided on the piezoelectric layer, in which, in the piezoelectric actuator, an active portion which is obtained by inserting the first electrode and the second electrode of the piezoelectric layer is provided, between the active portions adjacent to each other in the first direction, a groove portion is provided which is provided over the second electrode, the piezoelectric layer, the first electrode, and a portion of the vibration plate in a stacked direction.

Claim (Index 20):
A piezoelectric device comprising:\n a substrate in which a plurality of recessed portions are arranged in parallel in a first direction; and a piezoelectric actuator which has a first electrode provided on one surface side of the substrate with a vibration plate interposed therebetween, a piezoelectric layer provided on the first electrode, and a second electrode provided on the piezoelectric layer, wherein, in the piezoelectric actuator, an active portion obtained by inserting the first electrode and the second electrode of the piezoelectric layer is provided for each recessed portion, wherein the first electrode constitutes common electrodes which are provided commonly to a plurality of the active portions, wherein the second electrode constitutes an individual electrode independently provided for each of the active portions, wherein, in a second direction orthogonal to the first direction as an in-plane direction of the one surface of the substrate, an end portion of the first electrode is provided outside an end portion of the second electrode, and an end portion of the piezoelectric layer is provided between the end portion of the first electrode and the end portion of the second electrode, wherein, in the second direction, a leading-out wiring leaded out in the second direction from one end portion of the second electrode is provided, wherein, between the active portions adjacent to each other in the first direction, a groove portion provided over the second electrode, the piezoelectric layer, the first electrode, and a portion of the vibration plate in the stacked direction is provided, and wherein, in the second direction, an end portion of the groove portion is positioned outside an end portion of the active portion.
