ABSTRACT:
An electron beam device comprising an electron source having an electron-emitting device, a member to be irradiated with an electron beam disposed opposite to the electron source, and an electrically conductive spacer disposed between the electron source and the member to be irradiated with the electron beam, is characterized in that an electrode is disposed along an end portion of the spacer on the electron source side, and the electrode is disposed inside a region of a surface of the end portion of the spacer which is directed toward the electron source side.
