摘要： In the prior art, ejection openings are formed of different materials having respective wettability levels Thus, ink may disadvantageously be drawn toward a more wettable material and ejected obliquely. Further, if ejection is carried out with a horizontally dripping liquid adhering to ejection opening edges and an edge of a roof plate forming a part of each ejection opening, the ink droplets may disadvantageously be ejected obliquely to the direction in which they are originally ejected. According to the present invention, the ejection openings are formed of the same material to prevent the ejecting direction from being affected by the difference in wettability. Further, a resin is raised from the ejection opening portion to prevent the horizontally dripping liquid adhering to an ejection opening periphery from contacting ejected ink droplets during ejection. As a result, the ejected ink droplets are not affected by the horizontally dripping liquid during ejection.

摘要翻译： 在现有技术中，喷射口由具有各自润湿性水平的不同材料形成。因此，油墨可能不利地被拉向更可润湿的材料并倾斜地喷出。 此外，如果用附着在喷射口边缘的水平滴落液体和形成每个喷射口的一部分的顶板的边缘进行喷射，则墨滴可能不利地沿着它们最初喷射的方向倾斜喷出。 根据本发明，喷射口由相同的材料形成，以防止喷射方向受润湿性差的影响。 此外，树脂从喷射口部分升高，以防止在喷射期间粘附到喷射口周边的水平滴落的液体接触喷射的墨滴。 结果，喷射的墨滴不会在喷射期间受水平滴落液体的影响。

摘要： An ink jet recording head and a process for producing the same, and an ink jet recording apparatus are provided that improve the printing performance and also improve the production efficiency. A conjugated body 73 formed by conjugating silicon wafers 50 and 58 is cut, whereby nozzles 22 are opened, and cutting into head chip units is carried out. At this time, deep grooves 84 are formed on the surface of the silicon wafer 58 by anisotropic etching, and they are penetrated by etching on the opposite side. Grooves 90 are formed on the silicon wafer 50 by using the thus penetrated deep grooves 84 as a mask.
