Film-forming apparatus
Provided is a film-forming apparatus capable of cleaning a discharge apparatus under a state in which a film-forming space and a cleaning gas ambience are separated from each other while continuing to form a film on an object to be film-formed having a film-like shape. The film-forming apparatus includes a cleaning chamber configured to be connected to a film-forming space when a shutter is opened, and to be separated from the film-forming space and cause a cleaning gas to be discharged into an internal space when the shutter is closed; means for moving a discharge apparatus between a cleaning position inside the cleaning chamber and a film-forming position closer to a cylindrical member than the cleaning position; and a control apparatus that controls the discharge apparatus to discharge the raw material gas when the discharge apparatus is moved to the film-forming position, and controls the shutter to be closed so as to fill the cleaning chamber with the cleaning gas when the discharge apparatus is moved to the cleaning position.
