PROBLEM TO BE SOLVED: To provide a non-aqueous electrolyte secondary battery capable of being produced without causing wrinkling on a collector to be used for an electrode. SOLUTION: The non-aqueous electrolyte secondary battery comprises an electrode body having a positive electrode sheet, on which LixMO2 is applied as a positive electrode active material, and a negative electrode sheet, on which a carbon material capable of storing/releasing lithium ions is applied as a negative electrode active material, wound via a separator 5. A single-side thickness L of a positive electrode active material layer 22 is set within a predetermined range. |
