    • The present invention is intended to provide a method of manufacturing an ink jet head having good stable-ejection characteristics, and an ink jet head. The invention is an exemplary method of manufacturing an ink jet head having a cavity that contains liquid and a nozzle that communicates with the cavity, and ejecting the liquid contained in the cavity from an ejection orifice of the nozzle with using a nozzle opening at an opposite side of the cavity as the ejection orifice. The exemplary method includes making an ejection orifice on a side of the nozzle have a taper portion in which the diameter increases progressively toward the ejection orifice side and forming lyophobic films and lyophilic films alternately on the taper portion inside the nozzle so as to form a stack film, and forming a lyophobic film inside nozzle in which annular end surfaces of the lyophobic films and annular end surfaces of the lyophilic films are exposed alternately by grinding the stack film on the taper portion to expose a side section of the stack film.
    • 本发明旨在提供一种具有良好稳定喷射特性的喷墨头的制造方法和喷墨头。 本发明是一种制造喷墨头的示例性方法,其具有包含液体的空腔和与空腔连通的喷嘴,并且使用相反的喷嘴开口从喷嘴的喷射孔喷射容纳在空腔中的液体 作为喷射孔的腔的一侧。 该示例性方法包括在喷嘴侧制造喷射口具有锥形部分,其中直径朝向喷射口侧逐渐增加,并且在喷嘴内的锥形部分上交替形成疏液膜和亲液膜,以形成堆叠 膜,并且在喷嘴内形成疏液膜,其中疏液膜的环形端面和亲液膜的环形端面通过研磨锥形部分上的叠层膜而交替地暴露以暴露叠层膜的侧部。
