PROBLEM TO BE SOLVED: To easily design an inkjet head capable of easily controlling the ink discharge. SOLUTION: The position of a first nozzle 8 related to a pressure chamber row 11a located on the outermost from among pressure chamber rows 11a to 11d of a pressure chamber row group 12M is determined. Then, at the position away from the first nozzle 8 by a distance T1 which is calculated by T (a natural number)×(a reference dot spacing), the position of a second nozzle 8 related to the pressure chamber row 11b is determined. Then, in the case when T is an odd number, the position of a third nozzle 8 related the the pressure chamber row 11c is determined at a position away from the first nozzle 8 by a distance T2 which is calculated by (3.5×T±0.5)×(the reference dot spacing). Then, in the case when T is an odd number, the position of a fourth nozzle 8 related to the pressure chamber row 11d is determined at a position away from the first nozzle 8 by a distance T3 which is calculated by (4.5×T±0.5)×(the reference dot spacing).
