An electron-beam irradiation apparatus includes an evacuatable filament-electron gun chamber housing a filament and an anode and having an inactive-gas inlet through which an inactive gas flows in; an evacuatable treatment chamber connected to an exhaust system; and a separation wall for separating the filament-electrode gun chamber and the treatment chamber. The separation wall has an aperture configured to pass electrons and gas therethrough from the filament-electron gun chamber.
