<p>An ink jet printer head wherein an ink droplet is emitted from a nozzle (11) formed on the surface of a nozzle plate (1), and a metal layer (13) and a sulfur compound layer (14) are formed on the surface of the nozzle plate. Gold atoms in the metal layer and the sulfur atoms in the sulfur compound layer (14) are covalently bonded, and a thin film having a water repellency is formed. Since the ink does not reside on the nozzle surface, the ink droplet is not drawn by the residual ink and not deviated.</p> |
