The invention relates to an ink jet recording apparatus comprising a pressure chamber (1) for accommodating an ink liquid, a nozzle (2) communicating with this pressure chamber (1) for discharging said ink liquid, and pressure applying means for applying a pressure to said pressure chamber (1),
   wherein said pressure applying means includes a diaphragm (6) formed in said pressure chamber (1), and a piezoelectric element (5) made of a monocrystalline or polycrystalline piezoelectric member highly oriented along a polarization axis showing perovskite structure, mainly composed of lead zirconate titanate or barium titanate, for vibrating the diaphragm (6), and a specified voltage is applied at least to said piezoelectric element (5) when discharging said ink liquid into a recording medium disposed at the front side of said nozzle (2).
