    • A nozzle member that would give a stable flow of fluid and would realize a work of high quality, more particularly a nozzle member with a minute long through-hole; and a process for producing the same. The nozzle member is one for fluid nozzle having at least one through-hole parallel to a center of axle, which nozzle member is 100 to 10 μm in the diametric dimension of the through-hole, being 5 or greater in the ratio between length (L) and diameter (D) of the through-hole, L/D and made of a ceramic material of 95% or greater relative density. Such a nozzle member with multiple minute through-holes is produced by carrying out extrusion molding or casting molding in a state such that a filament consisting of a synthetic resin, a carbon material or a metal material is enclosed in the direction of the axle center of a nozzle member material, drawing out the filament from the molded item and performing defatting/sintering, or by, without removing of a filament consisting of a synthetic resin or a carbon material from the molded item, performing defatting/sintering in an oxidative atmosphere so that the filament is evaporated off or eliminated by fire.
    • 一种喷嘴构件,其将产生稳定的流体流动并且将实现高质量的工作,更具体地,具有具有微小长孔的喷嘴构件; 及其制造方法。 喷嘴构件是用于流体喷嘴的喷嘴构件,其具有平行于轴心的至少一个通孔,该喷嘴构件在通孔的直径尺寸中为100至10μm,长度之间的比率为5或更大( L)和通孔的直径(D),L / D由相对密度为95%以上的陶瓷材料制成。 这种具有多个微小通孔的喷嘴构件通过在由合成树脂,碳材料或金属材料组成的细丝沿轴心的方向封闭的状态下进行挤压成型或铸造成型而制造 喷嘴构件材料,从模制品中拉出细丝并进行脱脂/烧结,或通过不从合成树脂或碳材料组成的细丝从模制品中除去,在氧化气氛中进行脱脂/烧结, 灯丝被火蒸发掉或消除。
