Summary: | PROBLEM TO BE SOLVED: To provide a carbon material used for an electrode of a hybrid capacitor, of which the electron conductivity is increased.SOLUTION: A carbon material for a hybrid capacitor can be manufactured by a manufacturing method comprising the steps of: activating a carbonaceous raw material for manufacturing the carbon material, where a sodium hydroxide is used as an activator, and the sodium hydroxide is mixed by 1.9-2.8 times the mass of the carbonaceous raw material; and performing a thermal treatment on an activated material obtained by the activation step. In the activation step, the activated material has an amorphous crystal structure and a graphite crystal structure; and an activation temperature and an activation time are adjusted so that the ratio (Ig/Ia) of a peak intensity Ig originating from the graphite crystal structure to a peak intensity Ia originating from the amorphous crystal structure is 1.0-1.5 in an X-ray diffraction chart of the activated material.SELECTED DRAWING: Figure 2
