Abstract: PROBLEM TO BE SOLVED: To provide a field emission element capable of preventing an increase in electric power consumption, and capable of improving reliability of the element. SOLUTION: In a three-pole type field emission element, the field emission element has a gate electrode 205, an emitter 204, and an anode 207, and is constituted so as to connect a resistance 209 between the gate electrode 205 and an external terminal 206 of this gate electrode. A resistance value of this resistance 209 is set so as to satisfy a condition of being larger by about 10 times or more than a resistance value up to an external terminal 206 of the gate electrode from the gate electrode 205, and smaller in characteristic time than an inverse number of a driving speed. That is, a resistance characteristic of this resistance 209 is set so as to become small such as having no influence on a field emission characteristic in normal operation, and become large such as being capable of controlling a quantity of leakage current generated in a state of electrically connecting a field emission electrode to the other electrode.
