Abstract
A nozzle plate to be mounted on an ink jet print head includes a plate body on which is formed a plurality of jet aperture portions from which ink is jetted and a water-repellant film formed on this plate body. The diameter of jet aperture portions formed on the plate body and the diameter of water-repellant film apertures formed on the water-repellant film so as to connect with the nozzle apertures are the same diameter R3, so the ink jet flow can be accurately controlled.
