Abstract (en)
There is provided a method of manufacturing a liquid discharge head (100) to vibrate a nozzle plate (1) including a substrate (81) and a piezoelectric body (82) to discharge liquid. The method includes forming the piezoelectric body (82) on the substrate (81) at 450°C to 600°C and forming a nozzle orifice (4) penetrating through the substrate (81) and the piezoelectric body (82).
