Abstract: An electrode assembly according to an embodiment of the present invention has a structure in which a stack, comprising a first electrode, a second electrode, and a separator interposed therebetween, is wound. In the electrode assembly, the first electrode and the second electrode may each comprise: an uncoated portion formed at the longitudinal end thereof and not coated with an active material; and a coated portion coated with the active material layer. Furthermore, a first insulating layer and a second insulating layer may be disposed on a first surface of the first electrode and a second surface opposite to the first surface, respectively, wherein the first and second insulating layers each extend by a predetermined length from an area including the boundary between the coated portion and the uncoated portion toward the end of the uncoated portion.
