Abstract
The present invention provides a raw oil composition for manufacturing a carbon material for electric double layer capacitor electrodes, characterized in that the raw oil composition comprises 25 wt % or more of a saturated component and 16 wt % or less of an asphaltene component among the saturated component, an aromatic component, a resin component, and the asphaltene component obtained by developing of the raw oil composition by thin-layer chromatography; the raw oil composition has an average molecular weight of 960 or less; and the raw oil composition has an aromatic-carbon-fraction (fa) of 0.22 to 0.72. Use of the raw oil composition provides a carbon material for electric double layer capacitor electrodes that can exhibit high capacitance with high reproducibility without manufacturing synthetic pitch.
