| titleOfInvention | Electrostatic drive type ink jet head and method of manufacturing the same |
| abstract | PROBLEM TO BE SOLVED: To provide a diaphragm in which an insulating film is formed by a thermal oxidation method, but the diaphragm is deformed by a deformation stress due to a high temperature at that time, and as a result, ink ejection characteristics are varied and printing quality is changed. Had been reduced. The present invention solves the above-mentioned problems, has a small deflection of a diaphragm, is excellent in gap accuracy, is unlikely to cause a drop in ink ejection characteristics, suppresses internal generation of crystal defects, and has no danger of ejection failure due to ink leakage. To provide an electrically driven ink jet head. SOLUTION: An aluminum or tantalum electrode film 14 arranged opposite to a diaphragm 5 is connected to an anode, immersed in an aqueous solution of phosphate, and an oxide film is formed on the surface of the aluminum or tantalum electrode film 14 by anodic oxidation. 19 is formed. |
