An electron feeder for a flat-type luminous device capable of providing electrons sufficient to ensure the uniform luminance of a whole display section irrespective of a distance from an electron source. A plurality of front electrodes and a plurality of rear electrodes constituting an electron beam guide are arranged separate from one another in the direction of traveling of the electrons, respectively, and the front electrode and rear electrode corresponding to each other constitute each guide electrode section. The so-constructed guide electrode sections are alternately applied thereto two different voltages, resulting in the electron beam guide exhibiting the function of focusing electrons.
