The present invention provides an electron emission material that is excellent in electron emission characteristics, a method of manufacturing the same, as well as an electron emission element. The method is a method of manufacturing an electron emission material including a carbon material obtained by baking a polymer film. In the method, a polyamic acid solution is prepared in which at least one metallic compound selected from a metal oxide and a metal carbonate is dispersed; the polyamic acid solution thus prepared is formed into a film and then is imidized to form a polyimide film including the metallic compound; and then the polyimide film thus formed is baked to form the carbon material. The electron emission material is formed so that it includes a carbon material, a protrusion having a concavity in its surface is formed at the surface of the carbon material, and the protrusion includes a metallic element.
