摘要：
The invention provides a stock oil composition for needle coke for a graphite electrode, the stock oil composition having a 10 vol % distillation temperature of 280° C. or higher as the distillation property, and when separated into the aromatic component and non-aromatic component by elution chromatography, having an aromatic component content of 30-80 wt % with respect to the total weight of the stock oil composition and an aromatic component molecular weight of 255-1300, as well as a non-aromatic component normal paraffin content of at least 5 parts by weight with respect to 100 parts by weight of the aromatic component.
