PROBLEM TO BE SOLVED: To provide a carbonaceous material increasing the amount of intercalation of ion, when being used as a storage battery and achieving higher capacity of the storage battery. SOLUTION: The carbonaceous material has a layered structure, in which a plurality of amorphous parts are dispersed on a (002) plane and the average area of the amorphous parts is 1.5 nm<SP>2</SP>or more. Alternatively, the carbonaceous material has the layered structure, in which a plurality of amorphous parts are dispersed on the (002) plane and the proportion of the total areas of amorphous parts in the (002) to the sum of areas of amorphous parts and crystalline parts in the (002) plane is 30% or more. Because of such a structure of the carbonaceous material, when the carbonaceous material is used, for example, as a storage battery, the amount of intercalation can be increased and the capacity can be increased.
