PROBLEM TO BE SOLVED: To assure good air bubble discharge property and liquid supply amount to individual liquid chamber while suppressing crosstalk. ! SOLUTION: A droplet discharge head includes an individual liquid chamber 12 communicating with a nozzle 11, a common liquid chamber 15 which supplies liquid to the individual liquid chamber 12 through an ink flow path 44, a piezoelectric element 50 which generates pressure fluctuation at the individual liquid chamber so as to discharge a droplet through the nozzle, and a damper film 72 which forms a wall surface of the common liquid chamber that faces the ink flow path against the individual liquid chamber. At a position facing the damper film in the common liquid chamber, a rib 62 is provided in nozzle array direction which is contacted with the damper film when a liquid is sucked through the nozzle. !
