An ink-jet head of the present invention comprising a plurality of ink ejecting nozzles; a first flat plate forming therein a plurality of pressure chambers communicating with their respective nozzles; a second flat plate forming therein a common ink chamber to distribute and feed the ink to the pressure chambers; and a third flat plate interposed between the first flat plate and the second flat plate and forming therein a restricted passage to restrict an ink flow, one end of which is connected to the pressure chamber and the other end of which is connected to the common ink chamber. The restricted passage is formed in the third flat plate, to be elongated along a direction of a surface of the third flat plate and is extended in a direction parallel with a plane formed by the pressure chambers.
