<p>PURPOSE: A secondary battery is provided to minimize the transfer of external impact to an electrode group by mounting the electrode group into a case with the state of being mounted into an insulative pack, thereby stably protecting the electrode group. CONSTITUTION: A secondary battery(100) comprises: an electrode group(10) for charging and discharging; a case(20) in which the electrode group is mounted; terminals(30) electrically connected to the electrode group, and projected to the outside of the case; and a lead taps(40) electrically connected to the terminal and the electrode group; and an insulating pack(50). The insulating pack comprises insert parts(57) formed near edge of one side, and groove parts in which the insert parts are insert-combined to be positioned to corresponding with the insert parts, and is mounted into the case for insulating the electrode group from a housing.</p> |
