Abstract
The capacitance per volume of an electric double-layer capacitor can be increased by using a raw-material carbon composition for use in a carbon material for an electrode of the electric double-layer capacitor by applying an activation process, characterized in that the raw-material carbon composition has a volatile content of 1.3% by mass to 15% by mass (both inclusive), and microstrength of 5 to 30% when the volatile content is less than 6% by mass while microstrength of 5 to 20% when the volatile content is 6% or more.
