12 ABSTRACT: The invention relates to an ink-jet printing head comprising a plate-shaped starting body (19), in which several ink ducts extend, which merge at a flat side of the starting body into nozzles (23) and at the opposite side into separated pressure chambers (18). The ink-jet printing head has a diaphragm plate (9) which is common to all pressure chambers (18) and which is connected to a piezoceramic plate (10) made in one piece, which has at the area of each pressure chamber an embossed part. The embossed parts carry layer-shaped electrodes (13) pro- vided with electrical connections (14). These embossed parts extend at least in part above the area of the pressure chambers so that the electrical connections are connected outside the area of the pressure chambers to the electrodes (13).
