Abstract:
1. A liquid discharge head including a plurality of piezoelectric members each including a pressure chamber for applying to liquid a pressure for discharging the liquid, a first electrode provided on an inner surface side of the pressure chamber, and a second electrode provided outside the pressure chamber, the piezoelectric members generating the pressure by being deformed using the first electrode and the second electrode and being arranged in a first direction intersecting with a liquid flow direction and in a second direction intersecting with each of the liquid flow direction and the first direction so that the flow directions of the liquid flowing through the pressure chambers of the piezoelectric members are arranged along one another, the liquid discharge head comprising: a plurality of first common wiring lines commonly connected to the plurality of first electrodes arranged in the first direction; and a plurality of second common wiring lines commonly connected to the plurality of second electrodes arranged in the second direction, wherein the plurality of first common wiring lines is arranged in the second direction, and the plurality of second common wiring lines is arranged in the first direction.
