Abstract: PURPOSE: A needle shaped electric field emission electronic beam emitter and a manufacturing method thereof are provided to enlarge an electric field by using a needle shaped cathode substrate and a carbon nano-tube. CONSTITUTION: Carbon nano-tube paste is manufactured by mixing a carbon nano-tube, a sintering binder(23), and an evaporable solvent(24). The viscosity of the carbon nano-tube paste is 0.5 to 10000cP. The carbon nano-tube paste coats a needle shaped cathode substrate. The needle shaped cathode substrate in which the carbon nano-tube paste is coated is dried and sintered. A caliber of the carbon nano-tube is 1 to 50nm. A paste bearing substrate(11) is separated from the needle shaped cathode substrate.
