A nonaqueous electrolyte secondary battery includes a negative electrode plate, a negative electrode current collector lead joined to the inner peripheral end of the negative electrode plate, and a negative electrode current collector-exposed part where a negative electrode active material layer is not formed at the outer peripheral-side end. The negative electrode current collector-exposed part at the outer peripheral end comes in contact with a battery case, and in a plane vertical to the axis of an electrode body, a line connecting the axis and the center of a positive electrode current collector lead does not coincide with a line connecting the axis and the center between the coating end of the outer peripheral-side negative electrode active material layer of the negative electrode plate and the terminal part of the outer peripheral-side positive electrode plate.
