  "textContent": "An object of the present invention is to provide a negative electrode active material having excellent charge/discharge characteristics (charge and discharge capacities, initial coulombic efficiency, and cycle characteristics). The object is achieved by providing a negative electrode active material containing: a silicon-based inorganic compound (a) composed of silicon (excluding zerovalent silicon), oxygen, and carbon; and silicon (zerovalent) (b). The equivalent constituent ratio [Q units/(D units + T units + Q units)] indicating the chemical bonding state (D units [SiOC], T units [SiOC], Q units[SiO]) of the silicon (excluding zerovalent silicon) present in the silicon-based inorganic compound (a) is within the range of from 0.30 to 0.80 inclusive.",
