摘要：
An electron emitting element of the present invention includes an electron acceleration layer that includes insulating fine particles but does not include conductive fine particles, the electron acceleration layer being provided between an electrode substrate and a thin-film electrode. This electron emitting element accelerates electrons in the electron acceleration layer and emits the electrons from the thin-film electrode, when a voltage is applied between the electrode substrate and the thin-film electrode. Accordingly, the electron emitting element of the present invention makes dielectric breakdown hard to occur. Further, this electron emitting element is produced easily at low cost and capable of emitting a steady and sufficient amount of electrons.
