Abstract
The entire part of a rear surface of a nozzle plate excluding peripheral portions of nozzle holes is coated with a resist tape, and this nozzle plate is immersed in an electrolytic solution in which ions of a metal and particles of a water-repellent resin are dispersed to provide a plating thereon, and the plated nozzle plate in the electrolytic solution is then heated to a temperature that is higher than a melting point of the water-repellent resin, whereby an entire portion extending from a front surface of the nozzle plate and the nozzle holes contiguous to the front surface to the rear surface is provided with a eutectoid plating layer to suppress deviation of the passage of ink droplets due to wetting by an ink or the like.
