Zusammenfassung:Provided is a negative electrode for a lithium ion secondary battery capable of obtaining a lithium ion secondary battery having a high capacity and excellent charge-and-discharge cycle characteristics. A negative electrode for a lithium ion secondary battery (1) includes: a current collector (3) composed of a metal porous body having a three-dimensional network structure (2); and a negative electrode active material (4) held on the current collector (3). An overcoat layer (5) covering an outer surface of the current collector (3) is included, and the overcoat layer (5) includes hard carbon.
