Nonaqueous electrolyte secondary battery

A nonaqueous electrolyte secondary battery comprising:

• a positive electrode including a conductive positive electrode current collector and a positive electrode mixture layer provided on a surface of the positive electrode current collector and containing a positive electrode active material being capable of electrochemically inserting and extracting lithium ions;
• a negative electrode including a conductive negative electrode current collector and a negative electrode active material layer provided on a surface of the negative electrode current collector and containing a negative electrode active material being capable of electrochemically inserting and extracting lithium ions;
• a porous insulation layer interposed between the positive electrode and the negative electrode;
• and
• a nonaqueous electrolyte held between the positive electrode and the negative electrode,
• wherein after charging, when the porous insulation layer is removed and thereby a surface of the positive electrode mixture layer and a surface of the negative electrode active material layer are brought in contact with each other, terminals are provided, respectively, on the positive electrode current collector and the negative electrode current collector and a resistance value between the terminals is measured, the resistance value is 1.6 Ω·cm2 or more.
