Abstract: 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.
