Abstract: Provided are a carbon electrode particularly suitable to be used as a negative electrode of an energy storing apparatus and the like and a method for manufacturing the same by forming the carbon electrode by heat-treating a natural carbon material such as a natural fiber sheet including a natural fiber or cellulose sheet including a natural cellulose fiber which is a natural material other than a petroleum-based material or a petroleum-based synthetic material to reduce manufacturing cost, shorten a manufacturing process, minimize discharge of a hazardous substance, and uniformly maintain storage capacitance even in repeated charging and discharging when being applied to the energy storing apparatus. The carbon electrode includes any one of an alkali metal particle and an alkali earth metal particle having an average particle size of less than 100 nm which is formed on a surface in a process of carbonizing a natural carbon material.
