    Abstract: In the case where a secondary battery is repetitively curved, portions which tend to cause deterioration such as crack or breakage are, for example, a positive electrode tab and a negative electrode tab. This is because these portions are narrow projected portions, and tend to have low mechanical strength against repetitive curving in some cases. In view of the above, the positive electrode tab and the negative electrode tab are provided in portions relatively less affected by curving. More specifically, secondary battery includes a positive electrode, a positive electrode lead electrically connected to the positive electrode, a negative electrode, a negative electrode lead electrically connected to the negative electrode, a separator, and an exterior body wrapping the positive electrode, the negative electrode, and the separator. The positive electrode, the separator, the negative electrode, and the exterior body can be curved in a first direction. The positive electrode lead and the negative electrode lead are drawn from opposite sides of the exterior body.
