To manufacture a simple nozzle plate in which an adhesive hardly enters into a nozzle hole.

The nozzle hole 2 is formed in a substrate 1. A delivering face 1a of the substrate 1 is covered with a photo-curable resin 4, and the nozzle hole 2 is filled with the photo-curable resin 4. The substrate 1 is irradiated with UV light in the direction going toward the delivering face 1a from the back face 1b to cure the photo-curable resin 4. The back face 1b of the substrate 1 is covered with a photo-curable resin 14. A transparent film 17 is covered on the photo-curable resin 14 covered on the back face 1b. The photo-curable resin 14 is irradiated with the UV light in the direction of going toward the delivering face 1a from the back face 1b through the transparent film 17 to cure a part which does not overlap the shading region 18 of the photo-curable resin 14. By removing the transparent film 17, a cured resin part 15 and an uncured photo-curable resin 14 are exposed. The uncured parts of the photo-curable resins 4 and 14 are removed. The cured resin parts 5 and 15 are masked to form water-repellent films 3 and 13. The cured resin parts 5 and 15 are removed.
