Method of producing nozzle plate and said nozzle plate |
摘要 |
A nozzle plate includes a nozzle surface and a nozzle hole. The nozzle surface defines an ink ejection port. The nozzle hole includes a taper hole portion and a curved-surface hole portion. The taper hole portion has an inner surface of a truncated conical shape and has the smallest diameter at one end thereof. The curved-surface hole portion has an inner surface of a curved-surface shape. The inner diameter of the curved-surface hole portion gradually decreases as approaching from the one end of the taper hole portion to the ink ejection port.
