A water-repellent film exhibiting excellent water-repellency to a liquid containing a compound having a strong adsorptivity, a method for producing the same, and a nozzle plate are provided. A water-repellent film formed on the surface of an object to be processed, wherein at least the surface side is formed of a single water-repellent film made of a polymer of a fluoroalkyl-based silane compound, For example, it can exhibit excellent water repellency to a liquid containing a compound having a relatively high adsorptivity such as a surfactant or a resin.
