A droplet discharge apparatus includes: a plurality of tanks for respectively storing a plurality of types of function liquids; a plurality of pressure control valves for controlling a pressure of the plurality of types of function liquids supplied from the tanks to a predetermined pressure; a plurality of droplet discharge heads for respectively discharging the plurality of types of function liquids let out from the pressure control valves in the form of droplets; and a plurality of second supply tubes for respectively supplying the plurality of types of function liquids from outlets of the pressure control valves to inlets of the droplet discharge heads. Distances between the outlets and the corresponding inlets are different from one another depending on the second supply tubes. Lengths of the second supply tubes for supplying the same type of the functional liquid are equalized.
