| description | A main object of the present disclosure is to provide an anode active material with excellent capacity properties. The present disclosure achieves the object by providing an anode active material to be used in an alkaline storage battery, the anode active material including: a base material containing Ti and Cr, and including a BCC structure as a metastable phase; and a coating layer that coats the base material, and contains a catalyst metal and a metal with oxygen affinity that is more than oxygen affinity of Ti; wherein an oxide film is present in an interface between the coating layer and the base material; and when a first thickness TA (nm) and a second thickness TB (nm) of the oxide film are determined by Auger electron spectroscopy, a rate of the TA with respect to the TB, which is TA/TB is, for example, 1.50 or more. |
