<P>PROBLEM TO BE SOLVED: To provide an ink-jet head surely preventing short-circuiting of electrodes of neighboring pressure chambers, although the ink jet head is inexpensive. <P>SOLUTION: The ink-jet head includes: piezoelectric modules forming a plurality of pressure chambers; the electrodes formed on each piezoelectric module, with facing the plurality of pressure chambers; a nozzle plate with wiring transmitting an electric signal to the electrode; an insulating joint member joining the piezoelectric modules with the nozzle plate; an opening part penetrating the nozzle plate and the joint member and reaching the piezoelectric modules; and a conductor conducting the electrode with the wiring at the opening part. <P>COPYRIGHT: (C)2012,JPO&INPIT |
