Field emission type cathode, electron emission apparatus and electron emission apparatus manufacturing method

摘要

To form a sharp edge portions of an electron emission part of a field emission type cathode to face an electron application surface. At least an electron emission part of field emission type cathode (K) is constituted by stacking thin plate-like conductive fine grains and the field emission type cathode (K) is formed so that the plane direction of the thin plate-like fine grains of the electron emission part crosses an electron application surface. <IMAGE>
