PROBLEM TO BE SOLVED: To provide a positive electrode, in which a permeability of liquid nonaqueous electrolyte is improved and improvement in cycle life time of a nonaqueous electrolyte secondary battery is possible. SOLUTION: In the positive electrode containing a positive electrode active substance, an electroconductive agent and a binder, the electroconductive agent contains at least either of fibrous graphite material, whose maximum fiber length is not less than 50 μm or graphite material whose maximum particle size is not less than 50 μm, and carbon black whose average primary particle size is 10 to 100 nm. |
