PURPOSE: To uniformly and easily form an electron emitting electrode with high electron emitting efficiency. CONSTITUTION: This manufacturing method of this electron emitting element comprises a process for forming a cathode electrode 11 on a support body 10, a process for forming an insulating layer 12 on the support body 10 including the cathode electrode 11, a process for forming a gate electrode 13A on the insulating layer 12, a process for forming openings 14 making the cathode electrode 11 exposed on its bottom in at least the insulating layer 12, a process for forming electron emitting electrodes 17B made from a conductive composition containing conductive particles and a binder on the cathode electrode 11 exposed on the bottom of the openings 14, and a process for removing the binders on the surface layers of the electron emitting electrodes 17B so as to expose the conductive particles on the surfaces of the electron emitting electrodes 17B.
