Zusammenfassung:PROBLEM TO BE SOLVED: To provide a negative electrode for lithium secondary battery use which uses a silicon-containing material as a negative electrode active material and enables the improvement of cycle characteristics of a lithium secondary battery.SOLUTION: A negative electrode for lithium secondary battery use comprises a conducting metal foil, and a negative electrode active material mixture layer formed on a surface of the conducting metal foil, and including at least one selected from silicon and silicon alloys, a polyimide resin, and a lithium titanium complex oxide. The lithium titanium complex oxide is mixed with at least one selected from the polyimide resin and a polyamide acid resin.
