A manufacturing method of an ink-jet head comprises the steps of: laminating with an adhesive a first plate having a nozzle hole that ejects an ink droplet and a second plate having a communication hole; and applying pressure to the first and second plates in their laminated direction. In the step of laminating, an opening of the nozzle hole is included within an opening of the communication hole on an interface between the first plate and the second plate. In the step of applying pressure, pressure is applied to only a region outside of the opening of the communication hole with respect to a plane parallel to planes of the first and second plate.

Manufacturing method of ink-jet head

A process of manufacturing a nozzle plate for an ink-jet print head. The nozzle plate includes (a) a substrate having an outside surface which is to be opposed to a print media, an inside surface which is opposite to the outside surface and nozzle holes which are formed through the substrate so as to be open in the outside and inside surfaces, and (b) a non-wetting layer which has a non-wetting characteristic and which covers the outside surface of the substrate. The manufacturing process includes: (i) a masking step of applying a resist on the inside surface of the substrate, and charging the nozzle holes with the insulating material such that portions of the resist protrude outwardly from openings of the nozzle holes on the outside surface; (ii) a non-wetting-layer forming step of forming the non-wetting layer on the outside surface in a plating operation; and (iii) an unmasking step of removing the resist from the substrate.
