PROBLEM TO BE SOLVED: To provide an inkjet head which allows adjustment of drive voltage for each piezoelectric oscillators array, and is provided with a piezoelectric actuator having a group of productivity-improved piezoelectric oscillators. SOLUTION: A nonconductive fixed member of the piezoelectric actuator has discrete electrode conductive patterns 24, and conductive patterns 25 each as a common electrode for several electrodes, on surfaces (a front surface 16b and a back surface 16c) parallel to a direction of piezoelectric oscillators group arrays, and also has conductive patterns 26 and 27 conducting with common electrodes on a surface (a side surface 16d) perpendicular to the direction of piezoelectric oscillator group arrays and on a back side surface (a bottom surface 16e). Conductive patterns to be common electrodes on the respective surfaces are patterned so as to be conducted. An electric conductive adhesive with which a space between two piezoelectric oscillator arrays is filled and which is conducted to a common electrode pattern, is divided so as to divide the common electrodes for each piezoelectric oscillator array.
