  "textContent": "A secondary battery includes: a positive electrode; a negative electrode including a negative electrode active material layer on which a film including an organic substance is formed; and an electrolytic solution including a sulfur-containing cyclic compound, a fluorinated cyclic carbonic acid ester, an unsaturated cyclic carbonic acid ester, and a multi-nitrile chain compound. According to a mass analysis of the electrolytic solution using gas chromatography-mass spectrometry, a content of the sulfur-containing cyclic compound, a content of the fluorinated cyclic carbonic acid ester, a content of the unsaturated cyclic carbonic acid ester, and a content of the multi-nitrile chain compound in the electrolytic solution each satisfy the following relation: the content of the multi-nitrile chain compound > the content of the fluorinated cyclic carbonic acid ester > the content of the sulfur-containing cyclic compound > the content of the unsaturated cyclic carbonic acid ester, and the total sum of those contents is greater than or equal to 5.0 wt% and less than or equal to 11.0 wt%.",
