A nonaqueous electrolyte secondary battery includes a positive electrode ( 5 ), a negative electrode ( 6 ) and a porous insulation layer ( 7 ). The positive electrode ( 5 ) includes a positive electrode current collector ( 51 ) and a positive electrode mixture layer ( 52 ), and the negative electrode ( 6 ) includes a negative electrode current collector ( 61 ) and a negative electrode active material layer ( 62 ). After charging the nonaqueous electrolyte secondary battery, when a surface of the positive electrode mixture layer ( 52 ) and a surface of the negative electrode active material layer ( 62 ) are brought in contact with each other, terminals are provided, respectively, on the positive electrode current collector ( 51 ) and the negative electrode current collector ( 62 ) and a resistance value between the terminals is measured, the resistance value is 1.6 Ω·cm 2 or more. |
