Abstract

An electron emitting element (1) comprises a substrate (2), an upper electrode (3) and a particle layer (4) formed between the substrate (2) and the upper electrode (3). The particle layer (4) contains metal particles (6) having a high oxidation resistance and insulating particles (5) having sizes larger than those of the metal particles (6). The electron emitting element (1) emits electrons stably in vacuum and even in the atmosphere, hardly produces harmful substances such as ozone and NOx because the electron emitting element (1) involves no electric discharge, and is not oxidized and deteriorated. Hence, the electron emitting element (1) can continuously operate stably for a long period of time even in the atmosphere and has a long service life.
