Patent ID: 7530667

Claim:
A method of manufacturing a nozzle plate in which a liquid-repelling film is formed on a surface of a nozzle forming substrate having nozzle holes for ejecting liquid droplets, the surface being on a droplet ejection side of the nozzle forming substrate, the method comprising the steps of: a spreading step of spreading sealing members for sealing the nozzle holes, over the surface of the nozzle forming substrate on the droplet ejection side; a drawing step of drawing the sealing members by suction through the nozzle holes, from another side of the nozzle forming substrate opposite to the droplet ejection side; a first removal step of removing a surplus of the sealing members present on the surface of the nozzle forming substrate on the droplet ejection side; an application step of applying a liquid-repelling agent onto the surface of the nozzle forming substrate on the droplet ejection side; a curing step of curing the liquid-repelling agent applied to the surface of the nozzle forming substrate on the droplet ejection side; and a second removal step of removing the sealing members from the nozzle holes.
