Beschreibung
Zusammenfassung:	A non-aqueous electrolyte secondary battery comprises an electrode assembly having a positive electrode, a negative electrode, and a separator, as well as an electrolyte solution and a battery case. The battery case has an exterior package and a sealing plate. The positive electrode has a positive electrode tab at an end of the electrode assembly, and the negative electrode has a negative electrode tab at an end of the electrode assembly. The electrode assembly is accommodated inside the battery case in such a manner that the end having the positive electrode tab and the end having the negative electrode tab face the sealing plate. T1 and T2 have the meanings as defined in the claims and the description, and satisfy a relationship of the following expression (I).1.05≤T2/T1≤1.4 (I)
