ABSTRACT:
A method for manufacturing a liquid jet recording head comprises the steps of forming liquid flow paths on a roughly molded resin product by grooving by the irradiation of laser beams and/or forming discharge openings by drilling also by the irradiation of laser beams, and of moving in the direction of the optical axis of the laser beams a mask having opening patterns for grooving and/or drilling arranged for the optical path of the laser beams during processing by the irradiation thereof, hence preventing processing pitches from being deviated due to the thermal expansion or contraction of resin that may take place when grooves or holes are processed. In this way, it is made possible to form them on a resin ceiling plate in good precision with good production yield, and also, to contribute to reducing the costs of manufacture significantly.
