Abstract
A liquid ejecting head includes a flow path forming substrate in which a pressure generating chamber which communicates with a nozzle which ejects a liquid is formed by a partitioning wall, and a piezoelectric actuator in which a first electrode, a piezoelectric layer, and a second electrode are laminated, in which the piezoelectric layer includes a region which is interposed between the first electrode and the second electrode in a lamination direction, and in which when viewed in plan view from the lamination direction, the region overlaps at least a portion of the edges of each side of an opening of the pressure generating chamber on the piezoelectric actuator side and does not overlap one of the first electrode and the second electrode in at least a portion of the opening.
