PROBLEM TO BE SOLVED: To manufacture an inkjet head for jetting an ink by a specified jetting speed by suppressing variation of driving electric voltage values on every head. SOLUTION: The inkjet head is equipped with a process wherein based on a combination of a nozzle diameter of a cavity unit and a capacitance value of a piezoelectric actuator, a rule for combination of the cavity unit for jetting the ink at a specified speed under a specified driving electric voltage and the piezoelectric actuator is determined in advance, a process wherein the nozzle diameter on every cavity unit and the capacitance value on every piezoelectric actuator are respectively measured, and a process wherein based on the rule for combination, the cavity unit and the piezoelectric actuator having respectively corresponding nozzle diameter and capacitance value are selected and combined.
