摘要： An electron emitting element of the present invention includes an electron acceleration layer provided between an electrode substrate and a thin-film electrode, which electron acceleration layer includes (a) conductive fine particles and (b) insulating fine particles having an average particle diameter greater than that of the conductive fine particles. The electron emitting element satisfies the following relational expression: 0.3x+3.9≦y≦75, where x (nm) is an average particle diameter of the insulating fine particles, and y (nm) is a thickness of the thin-film electrode 3. Such a configuration allows modification of the thickness of the thin-film electrode with respect to the size of the insulating particles, thereby ensuring electrical conduction and allowing sufficient current to flow inside the element. As a result, stable emission of ballistic electrons from the thin-film electrode is possible.
