Zusammenfassung:An anode material for a lithium-ion secondary battery, includes a carbon material satisfying the following (1) and (2):(1) D90/D10 of a particle size on a volume basis is larger than 2.0 and less than 4.3;(2) N/S, which is a value obtained by dividing a number N of particles with an equivalent circle diameter of 5 μm or less based on a number standard in a total number of measured particles of 10,000, by a specific surface area S determined by nitrogen adsorption measurement at 77 K, is 750 (particles·g/cm2) or more.
