Provided is a droplet jetting applicator including: a droplet jetting head configured to jet liquid supplied from a liquid storage unit; a liquid supply unit configured to supply the liquid from the liquid storage unit to the droplet jetting head through a liquid supply channel; a first buffer liquid reservoir positioned closer to the droplet jetting head than the liquid supply unit in the liquid supply channel, and formed so that the inflow liquid drops thereinto; a liquid return unit configured to return the liquid from the droplet jetting head to one of the liquid storage unit and the first buffer liquid reservoir through a liquid return channel; and a second buffer liquid reservoir positioned closer to the droplet jetting head than the liquid return unit in the liquid return channel, and formed so that the inflow liquid drops thereinto.
