PROBLEM TO BE SOLVED: To provide a droplet discharge device which properly performs cleaning for resolving discharge failure according to a cause of the discharge failure in a nozzle that discharges droplets. ! SOLUTION: A droplet discharge device 11 includes: multiple nozzles 12 which discharge droplets; multiple supply passages 14 which supply a liquid to the multiple nozzles 12; multiple actuator 33 which change channel resistance of the multiple supply passages 14; a discharge failure detection part 42 which detects discharge failure of the droplets in the nozzles 12 and a cause of the discharge failure for each nozzle 12; a cleaning mechanism 50 which decompresses a space Ro, with which the nozzles 12 communicate, thereby performing cleaning for discharging the liquid from the multiple nozzles 12; and a control part 15 which controls the actuators 33 when the cleaning mechanism 50 performs cleaning. When the discharge failure detection part 42 detects the nozzle 12 in which the discharge failure occu |
