ABSTRACT:
To provide an ink ejecting device with high quality and excellent stability, three-layered laminated protective film is formed to cover an electrode which is formed on a ceramic element. The protective film is composed of an organic continuous film formed on the electrode as a first layer for covering surface unevenness. On the resultant smooth surface, a continuous inorganic film is formed as a second layer. Further, an organic layer is formed as a final layer.
