PROBLEM TO BE SOLVED: To provide an anode which can constitute a nonaqueous secondary battery having excellent charge/discharge cycle characteristics, a manufacturing method thereof, and a nonaqueous secondary battery using the anode.SOLUTION: A nonaqueous secondary battery anode includes, on both sides of a current collector, an anode mixture layer containing an anode active material and a binder, characterized in that a ratio B/A of peel strength A (N/m) at 90° between the anode mixture layer and the current collector on one side of the current collector to peel strength B (N/m) at 90° between the anode mixture layer and the current collector on the other side of the current collector is 0.85 to 1.15. A nonaqueous secondary battery includes the nonaqueous secondary battery anode. The nonaqueous secondary battery anode can be manufactured by a manufacturing method in which, before an anode mixture containing composition used to form the anode mixture layer is coated on the surface of the current collector, the current collector is subjected to heat treatment so that its surface reaches a specific temperature. |
