Abstract: Embodiments of the present application provide a case, a secondary battery, a battery pack, a vehicle, and a method for manufacturing a secondary battery. The case includes a bottom wall and a side wall, the bottom wall and the side wall defining an accommodating cavity with an opening at one end for accommodating an electrode assembly of the secondary battery; wherein, an outer surface of the side wall includes a coated region coated with an insulating coating, and the coated region extends, in a height direction of the side wall, from a side of the side wall that is close to the bottom wall to a position near an edge of a side of the side wall that is close to the opening, so as to reserve a non-coated region with a preset height on the outer surface of the side wall that is near an edge of the opening.
