ABSTRACT:
A piezoelectric ceramic plate has a plurality of grooves and partition walls formed in it. A cover plate is attached to the piezoelectric ceramic plate to cover the grooves to form interleaved ink channels and air channels. A flexible print board is adhesively attached to one end surface each of the piezoelectric ceramic plate and the cover plate. The ink supply ports formed in the flexible print board connect to the ink channels. A cover portion formed on the flexible print board covers the inlet ports of the air channels so that no ink enters the air channels. A first contact electrode formed on the flexible print board is electrically connected to metal electrodes in the ink channels. A second contact electrode is electrically connected to metal electrodes in the air channels.
