Abstract: PROBLEM TO BE SOLVED: To improve the ink droplet discharging stability with respect to the liquid room internal pressure change and the impact force and achieve a high speed printing capable of obtaining a high image quality by forming a liquid room partition wall with a vibrating plate and an electrocast metal integrally so as to improve the rigidity of a head constituent. SOLUTION: By driving a piezoelectric element 4 for generating the elongation in the lamination direction, a diaphragm part 12 of a vibrating plate 7 is deformed to the ink liquid room 11 side so as to press an ink inside the ink liquid room 11. Accordingly, ink droplets are discharged from a nozzle hole 16. In this case, since a liquid room partition wall 8 comprising the ink liquid room 11 is formed with the vibrating plate 7 and an electrocast metal integrally, the rigidity of the liquid room partition wall part can be improved so that resonance among the liquid rooms and vibration of a nozzle plate can be reduced with respect to the ink liquid room internal pressure change and the impact force by the piezoelectric element 4 for coping with a high density of the nozzle hole and a high printing speed, and thus the image quality can be improved.
