A secondary battery includes a positive electrode, a negative electrode, and an electrolytic solution including at least one kind of sulfonyl compounds that are represented by a chemical formula R1(—O—C(═O)—R2-S(═O)2—Rf1)n1 or the like. In the chemical formula, R1 represents of an n1-valent hydrocarbon group, an n1-valent oxygen-containing hydrocarbon group, an n1-valent halogenated hydrocarbon group and an n1-valent halogenated oxygen-containing hydrocarbon group. R2 represents one of a divalent hydrocarbon group and a divalent halogenated hydrocarbon group. Rf1 represents one of a halogen group and a monovalent halogenated hydrocarbon group. n1 is an integer of 2 or more.
