PROBLEM TO BE SOLVED: To surely prevent clogging in nozzles (1) when nozzle holes (2) are subjected to composite plating. SOLUTION: The composite plating prepared by dispersing polytetrafluoroethylene particles (5b) into an Ni-P matrix (5a) is formed on the surfaces of the nozzle holes (2). In forming such films (5), the nozzles (1) are vibrated in a solution while the solution is kept stirred and in addition, the solution is stirred within the nozzle holes (2) as well.
