Abstract
A secondary battery includes a cathode, an anode, and a nonaqueous electrolytic solution. The anode contains a carbon material and silicon oxide, and a weight ratio (%) of the silicon oxide with respect to a total of the carbon material and the silicon oxide is within a range of 0.01% to 20% both inclusive. The nonaqueous electrolytic solution contains an unsaturated cyclic carbonate ester.
