A negative electrode for a lithium secondary battery includes a negative-electrode active material having a specific surface area of Sx (m 2 /g) and an average particle size of Lx (μm), a fibrous conductive material having a specific surface area of Sy (m 2 /g) and an average length of Ly (μm), and a granular conductive material having a specific surface area of Sz (m 2 /g) and an average particle size of Lz (μm), in which letting the negative-electrode active material content be X, letting the fibrous conductive material content be Y, and letting the granular conductive material content be Z, Log ((SyY+SzZ)/SxX×10 −1 )×Log ((LyY+LzZ)/LxX×10 1 ) is defined as an electrode parameter, and the electrode parameter satisfies Log ((SyY+SzZ)/SxX×10 −1 )×Log ((LyY+LzZ)/LxX×10 1 )≧0. |
