PURPOSE: A secondary battery is provided to secure stability and reliability by blocking electrolyte not to electrically disconnect a cap-plate and an electrode terminal through electrolyte. CONSTITUTION: A secondary battery(100) includes: a case in which an electrode assembly(10) is housed; current collection units(50,60) which are electrically connected to the electrode assembly inside the case; a cap plate which is combined with one opened side of the case and seals the case; electrode terminals(21,22) which are electrically connected to the current collection unit and in which a part is exposed to the outside through the cap plate; and insulating parts(25,26,27) which electrically separates the cap plate and the electrode terminal. |
