Disclosed is a secondary battery, comprising: an electronic assembly; a cap plate which is arranged on the electronic assembly; an electronic terminal which is withdrawn on the cap plate; a current collecting member to mediate an electric connection between the electronic assembly and the electronic terminal; and a fuse unit which is formed on the current collecting member to block a current more than a predetermined block point. The fuse unit includes a break unit which is formed to surround a through hole formed in the current collecting member; and a block point adjusting unit which is formed on the break unit in a notch shape. According to the present invention, the secondary battery having high reliability is able to block the current at the designed overcurrent block point and precisely control the point to block a current pass. Also, the secondary battery can minimize decline of stiffness that may be caused due to a safety structure while providing the safety structure. |
