Ink jet head and production method of the same

摘要

An ink-jet head, comprises an ink chamber (5) in which ink is stored; a piezoelectric element (4) to jet the ink from the ink chamber; an electrode (7) to apply an electric voltage onto the piezoelectric element; and a layer (9) provided on the electrode by an electrodeposition method. The layer is subjected to a process to change a surface energy. <IMAGE>
