Claim:
A method of manufacturing a nozzle plate, comprising the steps of: providing at least one nozzle hole in a nozzle plate; providing a liquid-repelling film on a first surface of the nozzle plate, the liquid-repelling film being provided so as to block the at least one nozzle hole provided in the nozzle plate; performing semi-curing of the liquid-repelling film provided on the first surface of the nozzle plate and blocking said at least one nozzle hole; providing a mask having at least one mask hole on the semi-cured liquid-repelling film so that the at least one mask hole is in a position corresponding to a position of the at least one nozzle hole; after providing the mask having the at least one mask hole, applying a forced flow of material to the semi-cured liquid-repelling film at least in a region of the semi-cured liquid repelling film blocking the at least one nozzle hole to form at least one film hole in the semi-cured liquid-repelling film to unblock the at least one nozzle hole so as to provide a nozzle able to eject a liquid; removing the mask after forming the at least one film hole; and performing full-curing of the semi-cured liquid-repelling film after removing the mask.
