A liquid-droplet jetting apparatus which jets a liquid droplet of a liquid, includes: a liquid-droplet jetting head which has a nozzle for jetting the liquid droplet of the liquid; a maintenance mechanism which includes: a suction cap which comes into contact with and separates from the liquid-droplet jetting head and which faces the nozzle; a suction pump which sucks a fluid in a space defined by the suction cap and the liquid-droplet jetting head in a state that the suction cap comes into contact with the liquid-droplet jetting head; and a discharge tube which is connected to the suction pump and discharges the fluid flowing through the suction pump; and a maintenance controller which controls the maintenance mechanism.
