PROBLEM TO BE SOLVED: To adjust vibrations through the use of the number of nuts to be mounted, by sharing a nut adapted to the bore of an orifice, and to ensure a stable printing quality. SOLUTION: This inkjet recording apparatus comprises a main body 1 of a nozzle, which generates ink particles by applying the vibrations to ink jetted from a nozzle, an electrification electrode which electrifies the ink particles, and a deflecting electrode which deflects the electrified ink particles. In the main body of the nozzle, a nozzle body is arranged on the front side of a nozzle jacket 26; a resonant bar 23, which is elongated toward the nozzle jacket, is provided in the nozzle body; a piezoelectric element 24 for vibrating a resonant body is provided in the resonant bar; a fixing nut 25a for fixing the piezoelectric element to the resonant bar is provided at the leading end of the resonant bar; and a plurality of vibration adjusting nuts 25b are attached to the resonant bar.
