摘要

A nozzle plate 3, the nozzle 4 of the nozzle hole 34, a silicon resin layer on the discharge face side surface of the nozzle base material 31 of a Ni metal sheet forming the can to form a water-repellent layer 32, the nozzle contact liquid film of the base material 31 and the water-repellent layer (32) but not on the oxide film between the silicon resin layer. on the other hand, the nozzle base material 31 nozzle holes 34 of the wall surface (34a) has a natural oxide film or the nozzle base material 31 of the the oxide film 35 is formed as a separate internal liquid film is formed to improve.
