An image-forming device includes, in an envelope, an electron-emitting element for emitting an electron by applying a voltage between electrodes, an image-forming member for forming an image by irradiation with an electron beam emitted from the electron-emitting element, and a supporting member for supporting the envelope. The supporting member has an electroconductive film at an end portion and a side portion thereof, and is electrically connected through the electroconductive film to the electrode.
