<p>An ink jet recording head is described having a spacer (30) and including a pressure generating chamber (31), a reservoir (33), and an ink supply port (32) connecting them, a nozzle plate (40), hermetically fixed on a first side of the spacer (30), for generating ink droplets when receiving an ink pressure from the pressure generating chamber (31), a vibrating plate (20), hermetically fixed on a second side of the spacer (30), for pressing the pressure generating chamber (31), and piezoelectric vibrators (2) for pressing the vibrating plate (20), wherein the vibrating plate (20) has thin portions (21a, 21b) each occupying a large area so that the compliance of a regional area closer to the nozzle openings (41) is larger than that of a regional area closer to the ink supply port (32). <IMAGE></p> |
