A nonaqueous electrolyte secondary battery includes an electrode group
having a positive electrode and a negative electrode wound flatly by way
of an interposed separator, a positive electrode tab electrically
connected to the positive electrode, and projecting from a spiral winding
surface of the electrode group, a negative electrode tab electrically
connected to the negative electrode, and projecting from the spiral
winding surface, and a nonaqueous electrolyte, wherein the nonaqueous
solvent contains sultone compound including a ring having at least one
double bond, and a distance between the positive electrode tab and the
negative electrode tab is 6 mm to 18 mm.
