PROBLEM TO BE SOLVED: To provide a negative electrode material for a non-aqueous electrolyte secondary battery capable of improving the battery life as compared with the prior art, a negative electrode for a non-aqueous electrolyte secondary battery containing the negative electrode material, and a non-aqueous electrolyte secondary battery including the negative electrode. To do. SOLUTION: A negative electrode material for a non-aqueous electrolyte secondary battery, a negative electrode active material composed of a silicon-based material, a skeleton forming agent containing a silicate having a siloxane bond, the negative electrode active material and the skeleton. A negative electrode material for a non-aqueous electrolyte secondary battery including an interface layer formed at an interface with a forming agent and composed of an inorganic substance, a negative electrode for a non-aqueous electrolyte secondary battery containing the same, and a non-aqueous electrolyte secondary battery. be.
