  "textContent": "A negative electrode active material containing negative electrode active material particles. The negative electrode active material particles include silicon compound particles each containing an oxygen-containing silicon compound. The silicon compound particle contains at least one of LiSiOand LiSiO. The silicon compound particle has, in a Si K-edge spectrum obtained from a XANES spectrum: a peak P derived from the Li silicate and located near 1847 eV; and a peak Q gentler than the peak P and located near 1851 to 1852 eV. This provides a negative electrode active material that is capable of stabilizing a slurry when the negative electrode active material is used for a secondary battery, and capable of increasing the battery capacity by improving the initial efficiency.",
