ABSTRACT:
A nozzle plate for an ink-jet printer includes a base plate and a water-repellent film formed over one major surface of the base plate. The water-repellent film is subjected to heat treatment for a given processing time at a processing temperature higher than the softening point of the material forming the water-repellent film after forming a nozzle hole through the base plate and the water-repellent film by a nozzle hole forming process. The heat treatment softens and substantially flattens burrs in the water-repellent film formed in the nozzle hole forming process.
