Abstract

A negative electrode active material for a non-aqueous electrolyte secondary battery, wherein the negative electrode active material is represented by an elemental composition formula of Met-Si—O—C—H (wherein Metrepresents one alkali metal element or a mixture of alkali metal elements), including: a silicate salt made of a silicon-based inorganic compound and the alkali metal, and fine particles composed of silicon, silicon alloy, or silicon oxide being dispersed in the silicate salt; and a negative electrode active material for a non-aqueous electrolyte secondary battery, wherein the negative electrode active material is represented by an elemental composition formula of Met-Si—O—C—H (wherein Metrepresents one alkaline earth metal element or a mixture of alkaline earth metal elements), including: a silicate salt made of a silicon-based inorganic compound and the alkaline earth metal.
