Abstract: A nonaqueous electrolytic solution for a secondary battery exhibits excellent cycle characteristics even in high-temperature environments. The solution includes at least one of boric acid esters, acid anhydrides, cyclic carbonates having an unsaturated bond, cyclic carbonates having a halogen atom, cyclic sulfonic acid esters, and amines having an acetoacetyl group. A secondary battery having a positive electrode and a negative electrode makes use of this electrolytic solution.
