PROBLEM TO BE SOLVED: To provide a droplet ejection device which ensures stable ejection accuracy even when using high viscous ink. SOLUTION: The droplet ejection device includes: a droplet ejection head 60 ejecting ultraviolet ray-curable ink onto a substrate, ink packs 150, 151 feeding ink to the droplet ejection head 60; a first heater 20 heating the liquid ejection head 60, a second heater 21 heating an ink flow path between the droplet ejection head 60 and ink packs 150, 151, and a heater control part 25 controlling the temperature of the second heater 21 according to the amount of the ink fed to the droplet ejection head 60 from the ink packs 150, 151.
