PROBLEM TO BE SOLVED: To provide an inkjet head capable of increasing the number of taking out the heads on a silicon substrate, remarkably decreasing the cost, and preventing a driving frequency from decreasing by taking sufficiently largely the dimension of a common liquid chamber. SOLUTION: In a liquid droplet delivering head, a nozzle substrate 1 provided with a plurality of nozzles 2, a liquid chamber substrate 12 including a plurality of liquid chambers 3 communicating with respective nozzles and a plurality of electro-mechanical transducers, and a liquid feeding substrate 7 for feeding liquids to respective liquid chambers are successively laminated, and a driving IC 11 for driving the electro-mechanical transducers and respective electro-mechanical transducers are joined through wiring members, and electric voltages are loaded on respective electro-mechanical transducers to bend the electro-mechanical transducers, pressures are generated thereby to the liquid chambers 3, further a frame substrate 9 is provided on the opposite side to the side where the liquid chamber substrate 12 of the liquid feeding substrate is arranged, and a frame substrate 9 driving circuit member 11 is mounted.
