The method includes a heating wire (22) winding process, a supporting line (21) melting process, a coating process for coating an electrodeposition solution shielding means on the outer surface of wire (22) at predetermined intervals, an electrodepositing an electro-emitting material on the outer surface of wire (22), and a process for removing the electrodeposition solution shielding means coated on the wire (22), thereby partially electrodepositing the heating wire of cathode to limit the electro-emitting region.
