ABSTRACT:
A method of producing an inkjet head includes producing a flow path unit that includes plural ink flow paths that reach inkjet nozzles through pressure chambers; producing an actuator unit that has a thermal expansion coefficient different from that of the flow path unit, includes a piezoelectric ceramic sheet; laminating the flow path unit and the actuator unit through a heat-curable adhesive agent; heating the flow path unit and the actuator unit to a predetermined temperature; applying pressure on the flow path unit and the actuator unit against each other through the heat-curable adhesive agent, after the flow path unit and the actuator unit are thermally expanded to maximum sizes at the predetermined temperature and before the heat-curable adhesive agent is cured; and releasing the pressure applied on the flow path unit and the actuator unit after the heat-curable adhesive agent is cured.
