The charge and discharge characteristics of a lithium secondary battery are further improved. A negative electrode for a lithium secondary battery includes an organic skeleton layer containing an aromatic compound that is a dicarboxylic acid anion having two or more aromatic ring structures, and an alkali metal element disposed on oxygen contained in the carboxylate anion. A negative electrode active material having a specific surface area Sx (m 2 / g) and an average particle size Lx (μm), and a specific surface area Sy (m 2). / G), a fibrous conductive material having an average length Ly (μm), and a particulate conductive material having a specific surface area Sz (m 2 / g) and an average particle size Lz (μm), and a negative electrode active material Is X, the fibrous conductive material is Y, and the particulate conductive material is in the ratio of Z, Log ((SyY + SzZ) / SxX × 10 −1 ) × Log ((LyY + LzZ) / LxX × 10 1 ) Satisfies electrode parameters of ≧ 0.
