ABSTRACT:
A method of emitting electrons by applying a voltage between a voltage application electrode and a target to be irradiated with the electrons emitted from an electron emission electrode with a conical portion in an electron emission device. The voltage application electrode is formed to oppose the electron emission electrode so as to sandwich an insulating layer therebetween and the target. A charge of the electron emission electrode which is lost by electron emission during an electron emission operation is supplied after the electron emission operation is completed.
