PURPOSE: A secondary battery is provided to reduce electric resistance of a current collecting plate, to improve strength supporting an electrode assembly, and to obtain good weldability. CONSTITUTION: A secondary battery includes: an electrode assembly(200) in which a positive electrode, a negative electrode, and a separator are wound; a current collecting plate(100) which is coupled with the electrode assembly in order to be connected to the positive and negative electrodes; a case in which the electrode assembly and current collector are housed; and a cap assembly coupled with the case to be electrically connected to the current collecting plate. |
