PROBLEM TO BE SOLVED: To provide an ink-jet recording apparatus enabling stable recording at all times independently of an ink temperature, a temperature in the apparatus and an environment temperature and highly reliable printing without degrading an image quality. SOLUTION: In an ink-jet recording apparatus wherein ink drops are discharged by a pressure of ultrasonic beams projected by a piezoelectric element to fly to a recording medium, a temperature of an ink 14 is detected by a thermistor 17 and a frequency of burst waves for driving a piezoelectric body 11 by a driving IC22 is controlled to be changed in accordance with the detected temperature. The piezoelectric body 11 is not divided to arrays, but a lower layer electrode 20 of the piezoelectric body 11 is divided in arrays and set as individual electrodes. Lead electrodes 21 of arrays are set via the same distance on a supporting material 10 and are arranged in contact bond wiring with the individual electrodes 20 of the piezoelectric body 11 via an adhesive material. The lead electrodes 21 are connected by a bonding wire 23 to terminals of the driving IC22 which drives the piezoelectric body 11. |
