    • A fluid nozzle (10, 10A, 20) includes a nozzle chip (12) that includes a through hole (121) having an inlet port (121a) from which a fluid (Q) supplied to the fluid nozzle is introduced and an outlet port (121b) from which the introduced fluid is ejected; and a base metal member (11, 21) that supports the nozzle chip embedded in a rear portion (11a, 21a) of the base metal member. The fluid nozzle receives the fluid supplied to the rear portion from the inlet port and ejects the fluid from the outlet port. An exposed portion (11e, 21e) of the base metal member is covered with a ceramic coating (13, 13A, 23) so that the base metal member does not touch the fluid.
    • 流体喷嘴(10,10A,20)包括喷嘴芯片(12),其包括具有入口端口(121a)的通孔(121a),供给流体喷嘴的流体(Q)从该入口端口引入, (121b),引入的流体从其喷出; 以及支撑嵌入在所述基底金属构件的后部(11a,21a)中的所述喷嘴芯片的贱金属构件(11,21)。 流体喷嘴从入口接收从后部供给的流体,并从出口排出流体。 贱金属部件的露出部分(11e,21e)用陶瓷涂层(13,13A,23)覆盖,使得贱金属部件不接触流体。
