Zusammenfassung:	Provided is a lithium ion secondary battery which is provided with an appropriate amount of electrolytic solution and which has a long lifetime. The lithium ion secondary battery (1) is provided with: a power generating element (10) including a positive electrode (12) and a negative electrode (11) which are laminated via a separator (13); an electrolytic solution; and a package (30) in which the power generating element and the electrolytic solution are disposed. A thickness obtained by subtracting a thickness of the package (30) from a thickness of the lithium ion secondary battery (1) is not less than 1.05 times and not more than 1.15 times a thickness of the power generating element (10) in a state in which the electrolytic solution is not included.
