Zusammenfassung:PROBLEM TO BE SOLVED: To provide a nonaqueous secondary battery controlling gas generation caused by reaction of positive electrode active material with electrolyte liquid or the like, preventing deterioration of charging-discharging characteristics, and superior in cycle characteristics. SOLUTION: In a nonaqueous secondary battery including a positive electrode, a negative electrode and an electrolyte, organic phosphoric acid or salt thereof is contained in the positive electrode. Especially, the organic phosphate or the salt thereof is contained in the positive electrode by 0.01 to 1 wt.% relative to positive electrode active material.
