Abstract:
A method of producing a nozzle plate having nozzle holes for use in an ink jet head, comprising the steps of:stretching a predetermined number of resin lines, each having a cross section corresponding in shape to each of said nozzle holes of said nozzle plate in the same arrangement as that of said nozzle holes of said ink jet head,plating the peripheral surface of each of said resin lines with a metal, while maintaining the arrangement of said resin lines,forming a nozzle substrate so as to include said resin lines therein with said metal used in the plating of said resin lines,subsequently slicing said nozzle substrate, and thenremoving said resin lines from said sliced nozzle substrate, thereby forming said nozzle plate.
