摘要： An ink jet recording head having a spacer including a pressure generating chamber, a reservoir, and an ink supply port connecting them, a nozzle plate, hermetically fixed on a first side of the spacer, for generating ink droplets when receiving an ink pressure from the pressure generating chamber, a vibrating plate, hermetically fixed on a second side of the spacer, for pressing the pressure generating chamber, and piezoelectric vibrators for pressing the vibrating plate, wherein the vibrating plate has thin portions each occupying a large area so that the compliance of a regional area closer to the nozzle openings is larger than a regional area closer to the ink supply port.
