ABSTRACT:
A convex portion2having a specific sectional shape is formed on a substrate1between electrodes3and4, and a gap6is formed on a conductive film5, connecting the electrodes3and4, on the convex portion2, whereby the distance from the center of the gap6serving as a electron-emitting portion to the stagnation point is reduced so as to enhance an electron emission efficiency.
