The ink channels applied to a carrier part form a pre-fabricatable channel block together with this carrier part. A channel plate is secured either to that side at which the ink channels end free or to the back surface of the carrier part. In one embodiment, the channel plate comprises a layer plate having through holes into which the free ends of the ink channels equipped with the small piezo tubes are pluggable.
