ABSTRACT:
A multi-electron beam source comprising an electron-emitting element part includes: a plurality of electron-emitting elements provided two-dimensionally in a matrix-like arrangement on a substrate, with opposing terminals of the electron-emitting elements arranged adjacently in the column direction thereof being electrically connected to each other, terminals on the same side of all the electron-emitting elements in the same row being electrically connected, and the plurality of electron-emitting elements being arranged in "m" rows, "m" representing a number of two or more. In addition, a driving circuit drives the electron-emitting element part, grid electrodes modulate electron beams emitted from the electron-emitting elements, and a cut-off circuit cuts off the electron beams caused by spike noises superposed on driving pulse generated by the driving circuit part.
