Beschreibung
Zusammenfassung:	Provided is a negative electrode active material that can improve the discharge capacity per volume and/or charge-discharge cycle characteristics. The negative electrode active material according to the present embodiment contains an alloy phase and ceramics. The alloy phase undergoes thermoelastic diffusionless transformation when releasing or occluding metal ions. The ceramics is dispersed in the metal phase. The content of ceramics in the alloy phase is more than 0 to 50 mass% with respect to the total mass of the alloy phase and the ceramics.
