A droplet jetting applicator includes a droplet jetting head having an inside channel allowing a passage of the liquid supplied from a liquid accommodating part to jet the liquid flowing in the inside channel in form of droplets, a liquid supply channel communicating the liquid accommodating part with the inside channel of the droplet jetting head, a liquid supply part supplying the liquid from the liquid accommodating part to the droplet jetting head through the liquid supply channel, a liquid return channel communicating the inside channel of the droplet jetting head with the liquid accommodating part and a liquid return part interposed in the liquid return channel to return the liquid after passing through the inside channel of the droplet jetting head from the droplet jetting head to the liquid accommodating part through the liquid return channel.
