PROBLEM TO BE SOLVED: To provide a liquid jetting device capable of reducing cost by simplifying its structure and manufacturing process. SOLUTION: The liquid jetting device comprises a nozzle plate 17 having nozzle openings 3, a fluid passage forming plate 13 having a pressure generation chamber 2 communicating with the nozzle openings 3 and an ink reserving chamber 4, communicating with the pressure generation chamber 2, as a flow passage space except for the pressure generation chamber 2, a diaphragm 11 for sealing the openings by being laminated on the fluid passage forming plate 13 and a piezoelectric vibration element 6 in deflection vibration mode for generating pressure in the pressure generation chamber 2 by vibrating the diaphragm 11. As the pressure generation chamber 2 and the ink reserving chamber 4 are formed in a piece of fluid passage forming plate 13, it is possible to cut cost by reducing the number of parts of a recording head and simplifying the structure and the manufacturing process.
