<p>An electron emission device which eliminates a complicated process of forming a pinnacle shape, solves a problem with a boron nitride thin film to improve adhesiveness, and operates at a low voltage. A boron nitride carbon thin film (3) containing boron (composition ratio, x), carbon (composition ratio, y) and nitrogen (composition ratio, z) with composition ratios satisfying the relations, 0 ≤ x < 1, 0 ≤ y ≤ 1, 0 ≤ z < 1, is provided, electrically connected, on a substrate or a semiconductor substrate (silicon substrate (1), gallium nitride layer (2)) having irregularities on the surface thereof, a first metal body (lead electrode (5)) is provided, electrically insulated, on the thin film (3), and a second metal body (anode electrode (7)) is provided opposite to the thin film (3) and with a space from the first metal body (5).</p> |
