Abstract
The present invention relates to a secondary battery. The secondary battery includes a can configured to accommodate an electrode assembly; and a cap assembly bonded to an opening of the can. The cap assembly includes an upper cap provided in the opening and connected to an electrode tab of the electrode assembly and a lower cap configured to bond the upper cap to the opening. The lower cap includes a first bonding part bonded to a bottom surface of the upper cap to support the upper cap and a second bonding part formed on an outer circumferential surface of the first bonding part to fix the upper cap while being bonded to the upper cap.
