Abstract
A film-forming device disclosed is a film-forming device for forming a film on a metal foil having a porous portion on a main surface thereof by a gas phase method, and includes a film-forming region in which the film is formed on the metal foil, conveyors to provided downstream of the film-forming region and drawing the metal foil from the film-forming region, and a control unit that controls the stress applied to the metal foil from the conveyors to 21 N/mmor less. This provides a film-forming device which does not cause defects easily on a film-forming target metal foil.
