    摘要： A flat electrode body of a battery has a first-side curved end positioned on a first side of an electrode body width direction and a second-side curved end positioned on a second side. A positive electrode innermost curved portion of a positive electrode sheet is disposed inside the first-side curved end. When the dimension from a positive electrode connecting portion to the end on the first side of the electrode body is defined as a distance and the dimension from the positive electrode connecting portion to the end on the second side of the electrode body is defined as a distance, the positive electrode connecting portion being in the positive electrode protrusion wound portion and connected to a terminal connecting portion of a positive terminal member, the terminal connecting portion is connected to the positive electrode connecting portion at a position satisfying the condition Ha≧1.1Hb.

    摘要： A nonaqueous electrolyte secondary battery includes: a flat wound electrode body in which an elongated positive electrode, an elongated negative electrode, and an elongated separator (70) which electrically separates the positive electrode and the negative electrode from each other overlap each other and are wound in a longitudinal direction; and a nonaqueous electrolyte. The separator (70) includes a substrate layer (90) which is formed of a resin substrate and a heat resistance layer (80) which is formed on one surface of the substrate layer (90), and an adhesion strength between the substrate layer (90) and the heat resistance layer (80) is 0.19 N/10 mm to 400 N/10 mm.
