description A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution. The electrolytic solution includes a solvent and an electrolyte salt. The solvent includes a first ester compound and a second ester compound. The first ester compound is represented by R1-C(═O)-OR2, where each of R1 and R2 represents a first alkyl group, R1 has carbon number from 1 to 3 both inclusive, and the sum of the carbon number of R1 and the carbon number of R2 is from 3 to 5 both inclusive. The second ester compound is represented by R3O-FP(═O)-OR4, where each of R3 and R4 represents a second alkyl group, and the sum of the carbon number of R3 and the carbon number of R4 is from 2 to 10 both inclusive. The content of the first ester compound in the solvent is 30 vol % or more.
