喷墨头的制造方法、喷墨头以及喷墨记录装置
摘要：
本发明的实施方式提供了喷墨头的制造方法、喷墨头以及喷墨记录装置，需要通过保护膜绝缘电极，以使电极不与油墨接触。喷墨头包括：基板；喷嘴板，具有喷出油墨的喷嘴；压电体，具有倾斜面和多个槽，所述倾斜面设置在所述基板和喷嘴板之间，第一面在第一方向上具有第一宽度，与所述第一面相对的第二面在所述第一方向上具有比所述第一宽度宽的第二宽度且所述倾斜面从所述第一面的边向所述第二面的边连接，多个所述槽形成在所述第一方向上，横穿所述倾斜面；导电膜，端部从所述第一面以及所述倾斜面离开，且形成在所述压电体的槽的内面；以及绝缘膜，覆盖所述导电膜。
摘要（英）：

According to one embodiment, a method for manufacturing an inkjet head includes attaching a piezoelectric body facing the substrate, forming slanting side surfaces on the piezoelectric body, the slanting side surfaces extending between a first surface and a second surface of the piezoelectric body such that first surface has a remaining area that is less that a remaining area of second surface, forming a groove in the piezoelectric body from the first surface towards the second surface, the groove passing through two slanting side surfaces on opposite sides of the piezoelectric body, forming a conductive film on an inner surface of the groove, trimming portions of the conductive film proximate to the first surface and the slanting side surfaces such that the conductive film is separated from the first surface and the slanting side surfaces at outer edges of the groove, and forming an insulating film over the conductive film.
