Separated support tapes are attached to an electrode assembly which includes a negative electrode plate, a positive electrode plate, and a separator for performing charge and discharge operations. The separated support tapes are attached to a lower portion of the electrode assembly so as to allow the electrode assembly to be easily inserted into a can, while reducing the possibility of fire in a secondary battery caused by a hard short when the secondary battery is compressed due to external force applied thereto, preventing battery performance from being deteriorated by allowing electrolyte to sufficiently flow into a lower portion of the electrode assembly, and reducing a manufacturing cost of the secondary battery by minimizing the amount of separated support tape to be used.
