The electrode assembly includes a first electrode, a separator, and a second electrode alternately stacked and wound. The can has an accommodation part accommodating the electrode assembly therein, and the can comprises a first can and a second can having cylindrical shapes open in a direction facing each other. The insulator insulates an overlapping portion between the first can and the second can.
