The present invention is a discharge nozzle cleaning device for a droplet discharge device and is provided with: a cleaning fluid flow path (12) formed in a cleaning stage (11); a cleaning fluid supply device (15) that supplies cleaning fluid to the cleaning fluid flow path (12); and a cleaning control means (26) that controls the operation of immersing and cleaning a discharge nozzle (32) in the cleaning fluid supplied to the cleaning fluid flow path (12). A fluid repelling treatment layer (21) is formed on the upper surface of the cleaning stage (11) to prevent overflow of the cleaning fluid from the cleaning fluid flow path (12) onto the upper surface of the cleaning stage (11). With this constitution, the cleaning fluid does not overflow onto the upper surface of the cleaning stage from the cleaning fluid flow path. In addition, the discharge nozzle can be cleaned by a small amount of cleaning fluid because the cleaning fluid surface rises up from the upper surface of the cleaning stage because of the surface tension of the cleaning fluid. |
