Abstract:
A method for processing a discharge nozzle of a liquid jet recording head, comprising the steps of:bringing a mask plate, on which the shape of an ejection orifice to be formed is patterned, into close contact with a liquid ejection side of an ejection orifice forming plate on which a plurality of ejection orifices of a liquid jet recording head are to be formed; and emitting parallel laser beams from the mask plate side, thereby processing and forming a discharge nozzle in the ejection orifice forming plate, wherein the closely contacted mask plate and the ejection orifice forming plate are reciprocally scanned by one reciprocation or more along a direction parallel to an arrangement direction of the plurality of ejection orifices with respect to a laser beam emission area.
