An inkjet head having improved print image quality is provided. The inkjet head includes a nozzle plate having nozzles for discharging ink. Swelled portions are arranged that project from the outer surface of the nozzle plate that is the surface facing a printing medium when the inkjet head is in use. The nozzle plate has nozzles that penetrate the outer surface and inner surface of the nozzle plate. The outer surface side openings of the nozzles are disposed within the flat top surfaces of the swelled portions. This type of inkjet head does not require grinding of the entire surface of the outer surface of the nozzle plate, when the periphery of the outer surface side openings of the nozzles is to be flattened. If only the flat top surfaces of the swelled portions are ground, the periphery of the outer surface side openings of the nozzles can be flattened. The time needed to flatten the periphery of the outer surface side openings of the nozzles can be shortened. When the outer surface side openings of the nozzles are to be flattened, the outer peripheral edge of the outer peripheral side openings of the nozzles are not subject to unnecessary grinding. Thus, the outer peripheral edges of the outer surface side openings of the nozzles can be made sharp. The outer surface side openings of the nozzles which have sharp edges can stably discharge ink. An inkjet head having improved print quality can be achieved.
