PROBLEM TO BE SOLVED: To provide a liquid droplet discharging head capable of restraining a fluid crosstalk, a liquid droplet discharge device which has the liquid droplet discharging head, and a method for accumulating bubbles in the liquid droplet discharging head.;SOLUTION: The liquid droplet discharging head includes a plurality of liquid droplet discharging parts equipped with a discharging port 180 for discharging the liquid droplet, a pressure chamber connected with the discharging port 180 through a communication passage, a driving element for applying a pressure to the liquid in the pressure chamber, a supply passage for feeding the liquid to the pressure chamber and a recovery passage for collecting the liquid in the communication passage, and a storage part 231 which has a common supply passage 212 for feeding the liquid to the supply passage and a common recovery passage 214 provided with a dead water region and collects the liquid from the recovery passage and accumulates bubbles in the dead water region. In the liquid droplet discharging head, the pressure fluctuation generated in the pressure chamber at discharging the ink is apt to propagate to the common recovery passage 214 from the common supply passage 212.;COPYRIGHT: (C)2011,JPO&INPIT
