摘要

PROBLEM TO BE SOLVED: To provide an electron emitting element which hardly generates insulation breakdown and is produced easily at low cost and emits stably a suitable amount of electrons.SOLUTION: The electron emitting element 1 includes insulator fine particles 5 between an electrode base board 2 and a thin-film electrode 3, and has an electron acceleration layer 4 excluding conductive fine particles. The electron emitting element 1 emits an electron from the thin-film electrode 3 by accelerating the electron in the electron acceleration layer 4 when applying voltage between the electrode base board 2 and the thin-film electrode 3.
