Abstract
A liquid drop jet apparatus is provided which includes a plurality of nozzles to jet out a liquid droplet, a liquid room corresponding to the nozzles, a liquid supply path to supply a liquid into the liquid room, a vibration board to apply a pressure to the liquid in the liquid room, and an electromechanical converter to vibrate the vibration board. The vibration board has a thin region corresponding to a wall of the liquid room and a thicker region thicker than the thin region. A longitudinal length of the thin region is longer than a longitudinal length of the liquid room, and the thicker region includes an end corresponding to a side of the liquid supply path.
