Liquid discharge nozzle

Abstract

To provide a liquid discharge nozzle capable of discharging a liquid in a wide range regardless of the viscosity of the liquid.SOLUTION: A liquid discharge nozzle comprises: a liquid discharge port capable of discharging a liquid; and a liquid collision wall provided facing and separated away from the liquid discharge port in a liquid discharge direction. The liquid collision wall is positioned on a central axis along the liquid discharge direction of the liquid discharge port, and has a covering region that covers 5% to 99% inclusive of an opening projection area of the liquid discharge port when viewed from a direction facing the liquid discharge port.SELECTED DRAWING: Figure 2
