An ink-jet head in which an ink emitting surface (front surface) for emitting ink from ink channels partitioned by piezo-electric driving walls is opposite to an ink supplying surface (rear surface) for supplying ink to the ink channels, wherein the printed circuit board which covers the ear parts of ink channels provides, wiring electrodes to be electrically connected to connecting wires which are extended to the rear surface to drive piezo-electric elements, and a recessed area (to work as a common ink chamber) which faces to ink channels to supply ink to the ink channels.
