Claim 0:
1. A negative electrode for use in a non-aqueous electrolyte secondary battery, the negative electrode comprising:
a current collector comprising a porous metal body;
a first negative electrode material disposed in pores of the porous metal body and comprising a negative electrode active material, a conductive aid, and a binder, the negative electrode active material comprising a silicon-based material; and
a second negative electrode material disposed in pores of the porous metal body and comprising a skeleton-forming agent comprising a silicate having a siloxane bond,
the negative electrode having:
a pair of first regions each located in each outer portion of the current collector in a thickness direction of the current collector and containing the first negative electrode material and the second negative electrode material; and
a second region located at a center in the thickness direction of the current collector and containing the second negative electrode material but not containing the first negative electrode material.
