Claim 0:
1. A non-aqueous electrolyte secondary battery negative electrode, comprising:
a collector formed of a foamed metal body formed of Ni or a Ni alloy, and a negative electrode material disposed in pores of the foamed metal body,
wherein the foamed metal body has an average pore diameter of 500 μm or less and a porosity of 90 to 99%.
wherein the negative electrode material is a cured product of a composition comprising a negative electrode active material formed of a silicon-based material, a skeleton-forming agent comprising a silicate represented by the following formula (1), a conductivity aid, and a binder, and when the total solid content of the negative electrode active material, the skeleton-forming agent, the conductivity aid, and the binder is assumed to be 100% by mass, the content of the skeleton-forming agent is 3.0 to 40.0% by mass,
