ABSTRACT:
A manufacturing method for a nozzle plate including a plurality of nozzle holes may include the step of forming a plurality of through-holes extending through a plate member in a thickness direction of the plate member. The manufacturing method may also include the step of forming a water repellant film in a region of one surface of the plate member where apertures of the through-holes are not positioned. The manufacturing method may further include the step of pressing individual regions on the one surface of the plate member, the individual regions respectively including the apertures of the through holes, to separate at least portions of the water repellant film formed in the individual regions from the water repellant film formed on the one surface.
