Provided is a nonaqueous electrolyte secondary battery for large power supply applications, which has excellent cycle characteristics and is produced by a simple procedure. This nonaqueous electrolyte secondary battery is configured using a positive electrode, a negative electrode, a separator and a nonaqueous electrolyte. The positive electrode is configured of at least a positive electrode active material and a collector. The negative electrode is configured of at least a negative electrode active material (11) and a collector (10). Lithium titanate is contained as the negative electrode active material (11), and the collector (10) of the negative electrode is formed of aluminum having a perforated structure or an alloy of the aluminum. The negative electrode has a thickness (T) of from 0.4 mm to 5 mm (inclusive). |
