PROBLEM TO BE SOLVED: To provide a nozzle-plate manufacturing method which enables the simplification of a nozzle-plate manufacturing process and formation of a finer irregularity at a low cost, a liquid-droplet discharging head and a liquid-droplet discharging device. SOLUTION: The nozzle-plate manufacturing method by which a minute irregularity is formed around a nozzle hole for discharging the liquid droplet has a first process by which a mask 205 of the almost same pattern as a projection of the above irregularity is formed on the surface of a substrate 105 using a die 202A with the projection 202A1 corresponding to the projection or a recess of the above irregularity and a second process by which the minute irregularity is formed on the surface of the substrate 105 by etching the substrate 105 using the mask 205.
