An inkjet head comprising: a plurality of ink discharge sections each comprising: pressure chambers configured to store ink and to change pressure on the stored ink; nozzles communicating to the respective pressure chambers,through which ink can be discharged according to the change of pressure on the ink in the pressure chambers; and first individual ink ejection flow paths and second individual ink ejection flow paths which communicate to the respective pressure chambers and through which ink can be ejected from the pressure chambers without being supplied to the nozzles, wherein the nozzles are disposed at different positions in a predetermined direction; a first common ink ejection flow path which communicates to the first individual ink ejection flow paths of the plurality of ink discharge sections and into which ink can flow through the first individual ink ejection flow paths in a first flow-in section; and a second common ink ejection flow path which communicates to the second individual ink ejection flow paths of the plurality of ink discharge sections and into which ink can flow through the second individual ink ejection flow paths in a second flow-in section, wherein the plurality of ink ejection sections are disposed in such a positional relation that, as a position of the nozzles of the plurality of ink discharge sections is nearer to a one end in the predetermined direction of an arrangement range of the nozzles of the plurality of ink discharge sections, a corresponding position at which ink ejected from the ink ejection sections flows in in the first flow-in section is nearer to the one end in the predetermined direction in the first flow-in section and a corresponding position at which ink ejected from the ink ejection sections flows in in the second flow-in section is nearer to the one end in the predetermined direction in the second flow-in section, characterized in that a first direction of ejection of ink in the first flow-in section of the first common ink ejection flow path has a component opposite to a second direction of ejection of ink in the second flow-in section of the second common ink ejection flow path. a plurality of ink discharge sections each comprising: pressure chambers configured to store ink and to change pressure on the stored ink; nozzles communicating to the respective pressure chambers,through which ink can be discharged according to the change of pressure on the ink in the pressure chambers; and first individual ink ejection flow paths and second individual ink ejection flow paths which communicate to the respective pressure chambers and through which ink can be ejected from the pressure chambers without being supplied to the nozzles, wherein the nozzles are disposed at different positions in a predetermined direction; pressure chambers configured to store ink and to change pressure on the stored ink; nozzles communicating to the respective pressure chambers,through which ink can be discharged according to the change of pressure on the ink in the pressure chambers; and first individual ink ejection flow paths and second individual ink ejection flow paths which communicate to the respective pressure chambers and through which ink can be ejected from the pressure chambers without being supplied to the nozzles, wherein the nozzles are disposed at different positions in a predetermined direction; a first common ink ejection flow path which communicates to the first individual ink ejection flow paths of the plurality of ink discharge sections and into which ink can flow through the first individual ink ejection flow paths in a first flow-in section; and a second common ink ejection flow path which communicates to the second individual ink ejection flow paths of the plurality of ink discharge sections and into which ink can flow through the second individual ink ejection flow paths in a second flow-in section, wherein the plurality of ink ejection sections are disposed in such a positional relation that, as a position of the nozzles of the plurality of ink discharge sections is nearer to a one end in the predetermined direction of an arrangement range of the nozzles of the plurality of ink discharge sections, a corresponding position at which ink ejected from the ink ejection sections flows in in the first flow-in section is nearer to the one end in the predetermined direction in the first flow-in section and a corresponding position at which ink ejected from the ink ejection sections flows in in the second flow-in section is nearer to the one end in the predetermined direction in the second flow-in section, characterized in that a first direction of ejection of ink in the first flow-in section of the first common ink ejection flow path has a component opposite to a second direction of ejection of ink in the second flow-in section of the second common ink ejection flow path.
