Abstract: In the discharge apparatus, a stage on which a substrate having target discharge areas is placed moves relative to a discharge head unit. When at least one of a plurality of first discharge nozzles of the discharge head unit reaches one of the target discharge areas, the first nozzle discharges a first droplet of fluid material to the target discharge area. When one of a plurality of second nozzles of the discharge head unit reaches the target discharge area to which the first droplet has been discharged, the second nozzle discharges a second droplet of the fluid material to the target discharge area. A first nozzle row of the first nozzles and a second nozzle row of the second nozzles are separated by a predetermined distance in a direction of the relative movement of the stage and the discharge head unit.
