Method of producing an ink jet recording head and ink jet recording head

摘要

A method of producing an ink jet recording head, in which a discharge port surface (5b) provided with a discharge port (7), through which ink is discharged, is provided comprises a conductive treatment step of carrying out a conductive treatment of the discharge port surface (5b) in a state where a material is present in the portion of the discharge port (7), a removing step of removing the material to open the discharge port (7), and an electrolytic deposition step of electrolytically deposit a water repellent material in the conduction-treated region of the discharge port surface (5b). <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE> <IMAGE>
