An electrode assembly for a secondary battery that includes pressing parts are formed on separators surrounding positive and negative electrodes so that the electrode assembly can be bent in a zigzag shape to form a stacked structure, and thus the thermal stability of the electrode assembly can be improved and the stacked structure of the electrode assembly can be easily formed. In addition, electrolyte can easily permeate the electrode assembly. The electrode assembly includes separators, positive and negative electrode plates disposed between the separators, and pressing parts formed on the separators between the positive and negative electrode plates. Guide parts are formed at the pressing parts, and the separators are bent at the guide parts.
