The positive electrode includes a positive electrode active material. The electrolytic solution includes a cyclic sulfuric acid ester compound, a cyclic ether compound, and a chain alkyl dinitrile compound. A ratio of a weight (mg) of the cyclic sulfuric acid ester compound to a weight (g) of the positive electrode active material is from 0.01 to 2.",
