PURPOSE: A method for wet repelling treatment of a nozzle for an ink-jet printer head using an insulating film is provided to equally form nonconductor thin film in each nozzle, and to equally control the depth of wet repelling layers. CONSTITUTION: A method for wet repelling treatment of a nozzle(30) for an ink-jet printer head using an insulating film includes the steps of forming an equal nonconductor thin film(32) in the reverse side of the nozzle by using vacuum vapor deposition, forming a wet repelling layer(34) by plating the surface of the nozzle on the whole with wet repelling material, and improving the wet repellency by treating the nozzle in which the wet repelling layer is formed with heat, so that the wet repellent layer is selectively formed in only the surface of the nozzle.
