<p>A case for a secondary cell given in the present invention includes: a can which includes a lower plate and an upward side wall extended upward from the lower plate and has an internal space with an open top; and a cap which includes an upper plate and a downward side wall extended downward from the upper plate, has an internal space with an open bottom, and separates the internal space of the can from the outside by being inserted into the internal space of the can to make the lower end of the downward side wall be settled on the top surface of the lower plate. The downward side wall includes a combination projection which is extended to the outside and then extended downward. The upward side wall includes a bending unit which is bent to be settled on the top surface of the combination projection. The case for a secondary cell given in the present invention enables combination between the can and the cap without a part protruding to the outside, maintains the combination and sealing between the can and the cap even if internal pressure increases, and improves electrical conductivity with an electrode assembly.</p> |
