PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery excellent in high temperature characteristics. SOLUTION: In the nonaqueous electrolyte secondary battery, since at least one of compounds expressed in a chemical formula 1 is contained in a solvent, decomposition of electrolyte can be prevented under a high temperature environment, and excellent battery characteristics can be obtained while preserving and using under the high temperature environment. In the formula, R1 and R2 express a hydrogen group, a halogen group, a methyl group, an ethyl group or a group whose part of hydrogen is substituted by a halogen group. Either X or Y is sulfur, and the other denotes either sulfur (S) or oxygen (O). COPYRIGHT: (C)2009,JPOandINPIT
