PURPOSE: A secondary battery is provided to increase the combining strength between an electrode terminal and a bus bar, and to restrain the failure due to external vibrations and impacts, and to reduce contact resistance by increasing contact area between the electrode terminal and the bus bar. CONSTITUTION: A secondary battery(100) comprises a case, an electrode assembly mounted in the case, a cap plate covering the opening of the case, and an electrode terminal(60). The electrode terminal comprises: a first terminal plate(63), which is on the cap plate, electrically connected to electrode assembly; a second terminal plate(62) electrically connected to the electrode assembly through the first terminal plate, and having a through-hole; and a terminal coupling member(61), which is between the first terminal board and the second terminal board, comprising a connection part(61a) projected through the second terminal board. |
