摘要：
A nozzle plate for a liquid droplet discharge head to discharge a charged liquid droplet, includes a discharge port disposed on a nozzle face; a discharge chamber filled with liquid to be discharged from the discharge port; a nozzle hole extending from the discharge port in a thickness direction of the nozzle plate and communicating with the discharge chamber; a first electrode disposed at either the discharge chamber or the nozzle hole and contacting part of the liquid droplet; and a second electrode disposed on the nozzle face and neither connecting to the first electrode nor contacting the liquid droplet.
