1. An electrode assembly comprising:
a plurality of positive electrodes and a plurality of negative electrodes, alternately and repeatedly stacked;
a separator between the positive electrodes and the negative electrodes, respectively, to protrude from the positive electrodes and the negative electrodes and stacked such that surfaces at edges of the separator face each other;
a fixing member comprising an adhesive layer adhered to the surfaces of the separator at an end where an uncoated region of the positive electrodes and an uncoated region of the negative electrodes is formed, the adhesive layer being arranged at opposite sides of the electrode assembly; and
an insulating member adhered to an upper surface of the separator and a lower surface of the separator,
wherein the insulating member is disposed on the separator in a direction crossing the electrode assembly.
