摘要： PURPOSE: A secondary battery is provided to electrically connect an electrode terminal and a cap plate or can by comprising a sub-connect part, and to block current flowing to outside a secondary battery at overcharging by comprising at least two fuse parts in a current collecting part. CONSTITUTION: A secondary battery comprises: an electrode assembly(110) comprising a first and second electrodes, and a separator; a first current collector(150) electrically connected to the first electrode; a second current collector(140) electrically connected to the second electrode; a case(180) accepting the electrode assembly inside; and a cap assembly(170) comprising a cap plate(171). In the second current collector, at least two fuse parts(144,145) are formed. The second current collector comprises a first extension part(141) parallel to the bottom of the cap plate, and a second extension part(143) connected to the second electrode. The second current collector has a sub-connection part(160) to be electrically connected to the cap plate.
