PROBLEM TO BE SOLVED: To provide a droplet ejection device which can reduce the variation of the impact position of a droplet occurring between an end side nozzle and a central side nozzle among a plurality of nozzles arranged in one direction. SOLUTION: The end side nozzle 30a which is a nozzle out of a plurality of nozzles 30 arranged in one direction and is located on the end side in the arrangement direction has an ejection timing which is differentiated from the ejection timing of the central side nozzle 30b located closer to the central side than the end side nozzle 30a.
