Abstract: An ink jet head of the present invention compresses ink with an electrostatic force generated between each vibration plate and a counter electrode facing it. A glass substrate is formed with through holes in which a conductor is buried. A metal wiring pattern and conductor bumps are provided on the rear of each counter electrode. The conductor bumps and counter electrodes associated therewith are electrically connected together. Ink is fed from the rear of the glass substrate to a common ink chamber via a through hole assigned to ink feed. A metal wiring pattern on the rear of the glass substrate allows the conductor bumps to be arranged at any desired positions. The head does not need any flexible printed circuit board or any wiring substrate.
