Abstract
A multi-electron beam source comprises an electron emitting element part including: a plurality of electron emitting elements provided two-dimensionally in a matrix-like arrangement on a substrate; opposing terminals of 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, and a driving circuit part for driving said electron emitting element part. The multi-electron beam source has means for removing a spike noise superposed onto the driving pulse generated by said driving circuit part.
