Abstract

An electron-emitting device comprises a pair of oppositely disposed electrodes and an electroconductive film arranged between the electrodes and including a high resistance region. The high resistance region has a deposit containing carbon as a principal ingredient. The electron-emitting device can be used for an electron source of an image-forming apparatus of the flat panel type.
