Abstract
An anode active material including silicon-based particles, in which a ratio a/b of oxygen concentration a (% by mass) of the silicon-based particles determined by ONH elemental analysis, as to specific surface area b (m2/g) of the silicon-based particles determined by nitrogen gas adsorption, is a value of 0.03 or less.
