To provide a droplet ejection apparatus capable of inspecting droplets on an object to be coated in a short time, and further suppressing the generation of manufacturing failures of a coated body caused by an abnormal impact of the droplets.
The droplet ejection apparatus includes: a droplet ejection head 7 having a plurality of nozzles 7a for ejecting droplets and a plurality of piezoelectric elements corresponding to the respective nozzles 7a, and ejecting droplets to the object to be coated from the plurality of nozzles 7a according to the application of drive voltage for the respective piezoelectric elements based on the set value of the drive voltage applying to these piezoelectric elements; an imaging part 19 relatively moving with respect to the object to be coated, and sequentially imaging a plurality of inspection regions including the droplets on the object to be coated; and means for detecting the generation of attached droplets sticking to main droplets from captured images of the plurality of inspection regions to correct the set value of the drive voltage so as to avoid the generation of the detected attached droplets.
