A negative electrode for a non-aqueous electrolyte secondary battery capable of suppressing deterioration in durability and structural deterioration of the electrode and improving energy density and cycle durability by suppressing the generation of voids inside a porous metal body, and the same. To provide a non-aqueous electrolyte secondary battery comprising: The present invention has a current collector composed of a porous metal body, a negative electrode material arranged in pores of the porous metal body, and a second negative electrode active material, wherein the negative electrode material is , a first negative electrode active material arranged on the inner surface of the pores and composed of a silicon-based material; and a skeleton formed on the first negative electrode active material and containing a silicate having a siloxane bond. and a second negative electrode active material placed on the skeleton-forming agent.
