PROBLEM TO BE SOLVED: To provide an electrode material for an electric double layer capacitor having high output characteristics without depending on a temperature region for use, the method of manufacturing the same, and the double layer capacitor using the electrode material for the electric double layer capacitor. SOLUTION: There is provided an electrode material for an electric double layer capacitor obtained by carrying out alkali activation treatment on carbide. The rate of the half width (Δν1) of peak (G1) near 1,580 cm<SP>-1</SP>observed in the Raman spectrum of the carbide to the half width (Δν1) of peak (G1) near 1,580 cm<SP>-1</SP>observed in the Raman spectrum of the electrode material for the electric double layer capacitor obtained by carrying out alkali activation treatment is equal to or less than 10.
