PHO 80-509 1 ABSTRACT: In an ink jet printing head which comprises several nozzles, each of which having associated with it an essentially oppositely situated pressure chamber, there are provided at least two supporting sections which are linked in a stack-like manner opposite the nozzles and on which the pressure chambers are distributed in a staggered manner. The jet nozzle ducts which emerge from the pressure chambers on the supporting section remote from the nozzles and which lead to the nozzles are guided between the pressure chambers on the supporting section which is nearer with respect to the nozzles. According to a method of manufacturing such an ink jet printing head, first the supporting sections with the pressure chambers are individually finished after which they are linked in a stack-like manner and provided in a mould with an adapter piece in which the nozzle ducts emerging from the pressure chambers continue into further nozzle ducts leading to the nozzles.
