    Abstract: PURPOSE: To provide an electron emission element for efficiently supplying electrons from a cathode electrode film to an electron emission part. CONSTITUTION: This element is equipped with a substrate 21 and a plurality of projection parts 24 containing diamond that project from the substrate 21. Each of the projection parts 24 includes a columnar part 22 whose side face makes an inclination angle of about 90° to the surface of the substrate 21 and an acute part 23 positioned on the columnar part 22 and is equipped with an acicular body at its end. The columnar part 22 includes a conductive layer 22c in its upper part and the cathode electrode film 15 electrically connected to the conductive layer 22c is formed on the side face of the columnar part 22.
