Abstract
The method manufactures a nozzle plate. The method comprises: a liquid-repelling film forming step of forming a liquid-repelling film on an entire surface of a nozzle plate forming substrate having been formed with nozzles for ejecting liquid droplets; a liquid-repelling film solidification step of solidifying the liquid-repelling film formed in the liquid-repelling film forming step on a liquid droplet ejection surface of the nozzle plate forming substrate; a liquid-philic film forming step of forming a liquid-philic film on the liquid-repelling film formed on the entire surface of the nozzle plate forming substrate, after the liquid-repelling film solidification step; a liquid-philic film solidification step of solidifying the liquid-philic film formed in the liquid-philic film forming step; and a liquid-philic film removal step of removing the liquid-philic film formed on the liquid-repelling film on the liquid droplet ejection surface of the nozzle plate forming substrate, after the liquid-philic film solidification step.
