DETAILED DESCRIPTION - A carbon material has ratio (I110/I004) of peak intensity (I110) of (110) plane of graphite crystal and peak intensity (I004) of (004) plane obtained from a powder-X-Ray diffraction measurement of 0.1-0.6, average circularity of 0.80-0.95 and average face distance (d002) of the (002) plane of 0.337 nm or less, by X-ray diffraction method. In the carbon material, the total pore volume of pore with diameter of 0.4 mu m or less measured by nitrogen gas adsorption method is 8-20 mu l/g. When an optical structure of molded component cross section containing carbon material is observed with polarization microscope, an area is accumulated from the small structure of area, and the area of optical structure which covers area of 60% with respect to total area of all-optical structure, is set to SOP. When the number of structures is counted from the small structure of aspect-ratio and the volume-based average particle diameter and aspect-ratio in 60% area of structure with respect to total number of the structure is set to D50 and AROP, respectively. The volume-based average particle diameter (D50), aspect-ratio (AROP) and area of optical structure (SOP) satisfies the relations: 1.5 less than or equal to AROP less than or equal to 6, and 0.2x D50 less than or equal to (SOPx AROP)1/2 less than 2x D50. INDEPENDENT CLAIMS are included for the following:    (1) manufacture of carbon material, which involves pulverizing the coke at 1000 degrees C or more, graphitizing the pulverized particles at 2400-3600 degrees C, and contacting the pulverized particles with oxygen gas at 500 degrees C or more. The cross section of optical structure of coke is observed by polarization microscope, and an area is accumulated from the small structure. The area of optical structure which comprises 60% total optical structure area is 50-5000 mu m2;    (2) paste, which comprises the carbon material and binder; and    (3) electrode, which is formed by compressing the product obtained after coating and drying the paste on electrical power collector, with pressure of 1.5-5 ton/cm2.
