Zusammenfassung:A liquid discharge head (100) includes a nozzle plate (1) configured to vibrate to discharge liquid. The nozzle plate includes a substrate (81), a piezoelectric body (82), and a nozzle orifice (4). The piezoelectric body (82) is disposed closer to a discharge target than the substrate, the piezoelectric body (82) including lead zirconate titanate (PZT). The nozzle orifice (4) penetrates the substrate and the piezoelectric body. When a direction from one opening to another opening in the nozzle orifice is a discharge direction of the liquid, the PZT has a crystal structure extending parallel with the discharge direction.
