Zusammenfassung:	An inkjet print head is provided to secure high mounting density, and to reduce costs by including a substrate and barrier/orifice structure. An inkjet print head(14) comprises a substrate and barrier/orifice structure(28). The barrier/orifice structure is supported by the substrate, and defines nozzle arrays provided with a plurality of nozzle columns(60,70) and projection chamber arrays corresponding to the nozzle arrays. The nozzle includes each column of arrays arranged in a small group of the nozzle, and the small group includes at least two nozzles.
