PROBLEM TO BE SOLVED: To provide a liquid jetting device allowing the structure and manufacturing process to be simplified and the costs to be reduced. SOLUTION: The liquid jetting device is composed of a nozzle plate 17 in which a nozzle opening 3 is bored, a passage forming plate 13 furnished with a pressure generating chamber 2 in communication with the nozzle opening 3 and an ink storing chamber 4 in communication thereto to serve as a passage space other than the pressure generating chamber 2, a vibrating plate 11 laminated on the plate 13 to seal the opening, and a piezoelectric oscillator 6 of deflective vibration mode to vibrate the plate 11 for generating a pressure in the chamber 2. Because the pressure generating chamber 2 and ink storing chamber 4 are formed in one passage forming plate 13, a recording head can be constituted with less number of parts and the structure and manufacturing process can be simplified and the costs be reduced.
