PROBLEM TO BE SOLVED: To provide an electrode material for an electric double-layer capacitor, exhibiting high output characteristics in a low-temperature region, and to provide its production process and the electric double-layer capacitor. SOLUTION: In the process for producing the electrode material of an electric double-layer capacitor by performing alkali activation of a mixture of a carbonaceous material and an alkali compound, the temperature region in a system for performing alkali activation is 600°C-900°C, and the inside of the system for performing alkali activation is under inert atmosphere having a pressure of 0.11 MPa or higher.
