An electrode of a cold cathode fluorescent and manufacturing method thereof has an integral structure that makes it easy to increase the discharge area of the discharge portion and raise production output. The manufacturing method of the electrode has the followed steps: mixing metal powders and binders to form a mixture; shaping the mixture in an electrode die to form an electrode mold base; heating the electrode mold base until a sintering temperature to form an electrode; and compacting the electrode for increasing its intensity.
