1. A liquid droplet discharge head comprising:
an orifice plate that has a nozzle hole row in which a plurality of nozzle holes is formed in a row by press working, wherein liquid droplets are discharged to a to-be-landed-on member from the nozzle holes and land on the to-be-landed-on member, and plural dummy pressed points for making uniform opening directions of the nozzle holes are formed in the same orifice plate in which the nozzle hole row is formed, the dummy pressed points being formed outside an extent of the nozzle hole row in a direction in which the nozzle hole row extends and outside both ends of the nozzle hole row in the direction in which the nozzle hole row extends, wherein the dummy pressed points are dummy depressions in the orifice plate that do not pass through the orifice plate from a top side to an under side, and as a result of the dummy pressed points being formed in the orifice plate on both of the end sides of the nozzle hole row by press working, respective curved parts are formed at both of end parts, and a level part remains between the curved parts, and all of the nozzle holes are formed within the level part, and the dummy pressed points are formed in the curved parts, positioned outside the extent of the nozzle hole row, in the direction in which the nozzle hole row extends. |
