  "textContent": "An object of the present invention is to provide a nonaqueous electrolytic solution secondary battery that can improve trade-off relationships and exhibit good performance in paste properties, initial efficiency, cycle characteristics, low-temperature output, and the like. The present invention resolves the problem by using a multilayer-structured carbon material, as a nonaqueous electrolytic solution secondary battery negative electrode, which satisfies the following (a) and (b): (a) (Void fraction calculated from DBP oil absorption)/(Void fraction calculated from tapping density) is less than 1.01; and (b) Surface oxygen content (O/C) determined by X-ray photoelectron spectroscopy is 1.5 atomic % or more.",
