Zusammenfassung:PROBLEM TO BE SOLVED: To provide a drawing apparatus controllable of increased possibility of a trouble that a liquid with reduced amount of an additive caused by a deaerator, resides inside a drawing apparatus thereby the additive is reduced.SOLUTION: In the drawing apparatus, a discharging head for discharging a liquid is provided, the liquid is discharged from the discharge head to a medium for drawing, and the liquid is disposed on the medium for drawing. The drawing apparatus includes: a storage tank for storing the liquid; a first supply path, which is connected to the storage tank and a connection part, for supplying the liquid from the storage tank to the connection part; a circulation flow path, which is connected to the storage tank and the connection part, for returning the liquid from the connection part to the storage tank; a second supply path, which is connected to the connection part and the discharging head, for supplying the liquid from the connection part to the discharging head; and a deaerating means, which is provided on the second supply path, for deaerating dissolved gas of the liquid.
