Abstract:
本发明公开一种喷嘴板，其具有沿厚度方向贯穿该喷嘴板的喷嘴孔。所述喷嘴板包括形成于喷嘴孔处的排出口，若排出口的开口形状的四个角部的曲率记为R1、R2、R3和R4，则排出口的开口形状配置为近似满足方程式R1＝R2≥R3＝R4≈0。
Abstract(English):

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 approximately equal to 0.
