Abstract
A nozzle plate for an inkjet head including a substrate and ink ejecting holes formed in the substrate. An ink-repellent layer is formed on an ink ejecting side surface of the nozzle plate, and portions of the ink-repellant layer around the ink ejecting holes are selectively removed so that portions of the nozzle plate around the ink ejecting holes are exposed. Also, a method of producing a nozzle plate for an inkjet head is provided that includes preparing a nozzle plate which includes a substrate and ink ejecting holes formed in the substrate and has an ink-repellent layer formed on an ink ejecting side surface of the nozzle plate, and selectively removing portions of the ink-repellant layer around the ink ejecting holes to expose portions of the nozzle plate around the ink ejecting holes.
