Abstract
A liquid droplet jetting apparatus includes: a liquid droplet jetting head which has a liquid droplet jetting surface on which a plurality of nozzles are open and aligned in a row in a first direction; and a liquid droplet jetting state inspection unit which inspects liquid droplet jetting state of each of the nozzles, including: a liquid droplet landing body which has a landing surface facing the liquid droplet jetting surface and on which the liquid droplets jetted from each of the nozzles land, and which is configured to be relatively movable, with respect to the liquid droplet jetting head, in a second direction which is parallel to the liquid droplet jetting surface and intersects the first direction; and a landing detection mechanism which detects whether or not the liquid droplets have landed on a predetermined detection area provided on the landing surface of the liquid droplet landing body.
