Abstract: In accordance with one embodiment, an inkjet head comprises a plurality of groove-shaped pressure chambers formed on piezoelectric members of which the polarization directions are opposite, and a nozzle plate arranged at the lateral side of the pressure chambers across a lid section with high rigidity. A plurality of through holes connected to a plurality of nozzles formed on the nozzle plate is formed in the lid section. The inkjet head is set in a range of 10-25% before and after a center, that is, a length ratio where the relation between ejection voltage of ink ejected from the nozzles and a length ratio between the length of the through hole of the lid section in the longitudinal direction of the pressure chamber and the length of the pressure chamber in the longitudinal direction of the pressure chamber is minimized.
