    "patent_abstract": "This non-aqueous electrolyte secondary battery is characterized by comprising: a wound electrode body in which a positive electrode and a negative electrode are wound via a separator. Said battery is also characterized in that: when the separator is divided into five parts in the width direction and the five divided regions are defined as a region A positioned on one end of the separator in the width direction, a region B positioned on the other end of the separator in the width direction, a region C positioned in the center of the separator in the width direction, a region D positioned between the region A and the region C, and a region E positioned between the region B and the region C, then the void ratio of the region D and the region E is greater than the void ratio of the region A, the region B, and the region C.",
