PROBLEM TO BE SOLVED: To provide an inkjet head having a piezoelectric actuator with piezoelectric oscillator groups which enable drive voltage adjustment for each piezoelectric oscillator array, have a good productivity, and are excellent in ink discharge by suppressing speed variation, strokes and the like. SOLUTION: First and second piezoelectric oscillator groups corresponding to pressure generating chambers 3 are supported by nonconductive supporting members 16 conductor-patterned for each piezoelectric oscillator group array so as to divide a common electrode for each piezoelectric element group 14 array. The supporting members 16 are fixed to fixing members 17 having positioning sections. COPYRIGHT: (C)2006,JPO&NCIPI
