PROBLEM TO BE SOLVED: To provide a liquid droplet ejection device having improved operational reliability, stably supplying even a liquid of high viscosity to a head, and surely and smoothly jetting the liquid from the nozzle of the head. SOLUTION: The liquid droplet ejection device includes: a main liquid tank 10; a sub tank 2 for temporarily storing the liquid from the liquid tank 10 and having a supply flow path disposed from a tank bottom surface to the ejection head 1; the ejection head 1 having an internal flow path 15 and the ejection nozzles; a main heater 17a for heating the liquid in the internal flow path 15 of the ejection head 1, so as to enhance the flowability of the liquid; and a sub heater 17b for previously heating the liquid in the supply flow path of the sub tank 2, so as to enhance the flowability of the liquid.
