Abstract
Disclosed is a battery pack that can improve bonding strength between a bare cell and a case by combining a beading part of a bare cell with a projection on an inner surface of a case. The battery pack comprises a bare cell and an upper case. The bare cell includes an electrode assembly, a can receiving the electrode assembly, and a cap assembly covering an upper part of the can. The can includes a beading part inwardly pressed from an outer surface of the can. The beading part is at a higher position than an upper part of the electrode assembly. The upper case covers the beading part and upper part of the can, and includes a projection formed on an inner surface of the upper case. The projection is combined with the beading part of the can.
