ELECTRON EMISSION ELEMENT AND ELECTRON EMISSION ELEMENT FABRICATION METHOD

WIPO Patent Application WO/2007/037170

A1

An electron emission element (2) includes an electron emission unit (6) made of diamond. When an electron emission current value is equal to or above 10 μA in the electron emission element (2), a deviation of the electron emission current value for one hour is within ± 20%. Moreover, the number of generations of a stepwise noise in which the electron emission current value changes stepwise is once or below per 10 minutes.
