PROBLEM TO BE SOLVED: To provide a positive electrode for nonaqueous electrolyte secondary battery in which lowering of electrode capacity is prevented by suppressing exfoliation of an active material when repeating charge/discharge cycle, and to provide a manufacturing method of a positive electrode for nonaqueous electrolyte secondary battery, and a nonaqueous electrolyte secondary battery using the positive electrode for nonaqueous electrolyte secondary battery.SOLUTION: In the positive electrode for nonaqueous electrolyte secondary battery having an electrode mixture containing a positive electrode active material capable of absorbing and desorbing lithium, a collector of three-dimensional porous aluminum has holes defined by a metal wall, and the holes are filled with the electrode mixture, and the metal wall is in contact with the electrode mixture via a coating film formed of a conductive additive and a polymeric binder. A manufacturing method of a positive electrode for nonaqueous electrolyte secondary battery, and a nonaqueous electrolyte secondary battery using the positive electrode for nonaqueous electrolyte secondary battery are also provided. |
