    摘要： A negative electrode for a nonaqueous electrolyte secondary battery includes a negative-electrode current collector, a first negative-electrode active material layer, and a second negative-electrode active material layer. The first negative-electrode active material layer is formed on the negative-electrode current collector. The first negative-electrode active material layer contains graphite as a first negative-electrode active material. The second negative-electrode active material layer is formed on the first negative-electrode active material layer. The second negative-electrode active material layer contains a lithium titanate composite oxide as a second negative-electrode active material.
