<p>PROBLEM TO BE SOLVED: To obtain an electron-emitting element as an electron beam source, which has stable and uniform electron-emitting characteristics, and by which efficiency improvement of electron emission can be aimed at and a high-quality image forming device can be realized. SOLUTION: An underlayer 6, which is composed of magnetic particles having a convex part 7 with a height in the range of 1 nm to 10 nm, is formed between electrodes 2, 3, and a conductive film 4 is formed on the underlayer 6, and afterwards an electron-emitting part 5 is formed by performing current-fed forming. Hereby, the position and the shape of the electron emissive part 5 can be controlled precisely, and the uniformity of element characteristics can be realized.</p> |
