PROBLEM TO BE SOLVED: To provide a liquid droplet discharging device which can easily and surely adjust a temperature of a liquid in a cavity of a liquid droplet discharging head without using various kinds of sensors. SOLUTION: The liquid droplet discharging device includes an actuator driven by a driving circuit, and a vibrating plate displaced by driving of the actuator. The liquid droplet discharging device is equipped with a plurality of the liquid droplet discharging heads for driving the actuator by the driving circuit and discharging the liquid in the cavities as liquid droplets from nozzles. A temperature adjusting means is set, which detects residual vibration of the vibrating plate and adjusts the temperature of the liquid in the cavities of the liquid droplet discharging heads on the basis of a vibration pattern of the detected residual vibration of the vibrating plate.
