<p>Provided is an inkjet head comprising pressure chambers that pressurize the ink stored therein, nozzles that are positioned on the front surface-side of the pressure chambers and discharge the ink from within the pressure chambers, and supply channels that are positioned on the rear surface-side of the pressure chambers and supply the ink to the pressure chambers, said inkjet head being characterized in that the cross sections of the junctions of the pressure chambers and the supply channels are such that the cross section of one pressure chamber has a single overlap region where the cross section of the pressure chamber and the cross section of the supply channel overlap, and in that if S1 is the cross-sectional area of the one pressure chamber, S2 is the cross-sectional area of the supply channel, and S3 is the cross-sectional area of the overlap region (S3 > 0), the relationships S3 < S1 and S3 < S2 are fulfilled.</p> |
