A droplet ejecting apparatus includes: droplet quantity evaluation means, wherein the mass of a droplet ejected onto an article is measured, and a measurement signal is generated based on the measurement result; feedback control means, wherein said measurement signal is compared with a respective reference value and then a control signal is generated based on the result of comparison; and droplet ejecting means for adjusting the amount of ejection for the droplet on the basis of said control signal. In the apparatus, the amount of droplets ejected from a droplet ejecting means can be accurately determined in real time, and the variation in the amount of ejected droplets, the presence thereof and the deviation of the arrival position thereof can also be determined.
