Ink jet print head and method of manufacturing the same.

摘要

A method for manufacture of an ink jet head comprises the process of forming a head main body by providing a positive resist layer to constitute ink passages for a substrate having ink ejection pressure generating means and then a ceiling member therewith; forming a carbon-contained film for the surface where the ink discharging ports of the head main body are formed; conducting a fluoric plasma treatment given to the carbon-contained film by utilizing a hydrofluoride compound; and removing the positive resist layer. With this method, an F-C coupled water repellent film is formed on the discharging port formation surface of an ink jet recording head evenly with a desirable bonding capability to enhance the reliability of water repellency. <IMAGE>
