摘要:
An electron emitting device 2 comprises an electron emitting portion 6 made of diamond. At an electron emission current value of 10 μA or more, a deviation of the electron emission current value over one hour is within ±20% in the electron emitting device 2. The number of occurrence of step-like noise changing the electron emission current value stepwise is once or less per 10 minutes.
