A shell includes an insulating layer provided at an outer surface of the shell and including a repair part formed of a curable material and having a shape of a mushroom. The repair part includes an upper part having a shape of a cover of the mushroom and a lower part having a shape of a stem of the mushroom. The lower part is embedded in the insulating layer, the upper part protrudes from the insulating layer, and a lower surface of the upper part covers at least a portion of an upper surface of the insulating layer. In a cross section of the repair part perpendicular to a surface of the insulating layer, a longest dimension of the upper part is greater than or equal to a sum of a width of the lower part and a creepage distance of a battery.
