Zusammenfassung:PROBLEM TO BE SOLVED: To provide a negative electrode material which can construct a lithium ion secondary battery excellent in both input/output characteristics and life characteristics.SOLUTION: The negative electrode material for a lithium ion secondary battery comprises: a carbon material A containing agglomerated particles of flake graphite particles; and a carbon material B containing spherical graphite particles. The negative electrode material has the pore volume of 0.9-1.3 ml/g, the specific surface area of 4.0-6.0 m/g, and the tap density of 0.75-0.95 g/cm.
