Abstract

A nozzle plate having a nozzle hole that penetrates through the nozzle plate in a thickness direction is disclosed. The nozzle plate includes a discharge outlet that is formed at the nozzle hole, and provided curvatures of four corner portions of an opening shape of the discharge outlet are denoted as R1, R2, R3, and R4, the opening shape of the discharge outlet is configured to approximate the equation R1=R2≥R3=R4≈0.
