Abstract
The plurality of pressure compartments includes a first pressure compartment and a second pressure compartment located next to the first pressure compartment in the first direction. The plurality of nozzles includes a first nozzle that is in communication with the first pressure compartment and the second pressure compartment in a shared manner. The piezoelectric element includes a first active region where the piezoelectric body is sandwiched between the common electrode and, among the plurality of individual electrodes, a first individual electrode. The first active region is located to span from at least a part of the first pressure compartment to at least a part of the second pressure compartment as viewed in the second direction.
