Abstract:
A liquid ejecting head includes a line of first pressure chambers, a line of second pressure chambers, a line of nozzles including nozzles arranged in a first direction, first piezoelectric bodies, first individual electrodes, a first common electrode, second piezoelectric bodies, second individual electrodes, a second common electrode, a wiring member, a first individual line that electrically couples the first individual electrode to the wiring member, a first common line that electrically couples the first common electrode to the wiring member, a second individual line that electrically couples the second individual electrode to the wiring member, and a second common line that electrically couples the second common electrode to the wiring member. The wiring member is electrically coupled to the first common line at a position shifted to one side in the first direction relative to a center in the first direction of the lines of first and second pressure chambers, and the wiring member is electrically coupled to the second common line at a position shifted to another side in the first direction relative to the center in the first direction of the lines of first and second pressure chambers.
