Abstract
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.
