ABSTRACT:
In an ink jet head nozzle plate manufacturing method, a laser beam is generated using a laser beam source. A direction of the laser beam is changed using a mirror that reflects the laser beam. The laser beam reflected by the mirror is condensed using micro-lenses arranged on a common plane. Nozzle openings are formed in a nozzle plate using the laser beam condensed by the micro-lenses.
