PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery with large capacity and less gas generation. SOLUTION: An active material and a binder are kneaded to obtain paste A, a conductive material and a thickening agent are kneaded to obtain paste B in which the median diameter of the conductive material is 0.2-1 μm, the paste A and the paste B are mixed to obtain paste C, and the paste C is applied to a current collector, dried, then pressed to manufacture a positive electrode. As the thickening agent, a polymer containing an acrylonitrile unit and -(CH2 )n - structure (wherein, 6<=n) is used. |
