Abstract
A method of manufacturing an ink-jety recording head in which an ink supply port forming substrate , a common ink chamber forming substrate , and a nozzle plate are bonded together by inserting between them thermally fusible films and respectively, in which are formed through holes and at two or more positions, and by also filling the film through holes with an adhesive that is mixed with a gap material G for adjusting the thicknesses of the thermally fusible films when they are fused, so as to form a flow path unit ; and then the flow path unit and the actuator units are bonded together by inserting between them a thermally fusible film , in which are through holes at two or more positions, and by also filling the through holes with an adhesive that is mixed with a gap material G for adjusting the thickness of the thermally fusible film when it is fused.
