    摘要: 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.
