Disclosed is an electrode assembly in which a first electrode and a second electrode having a sheet shape and a separation film interposed therebetween are wound based on an axis to define a core and an outer circumference. The first electrode and the second electrode respectively includes an uncoated portion not coated with an active material layer on a longer edge end; and a coated portion having an active material layer coated on a region excluding the uncoated portion. The first electrode includes an insulation layer that simultaneously covers at least a portion of the uncoated portion and at least a portion of the coated portion along a winding direction. The uncoated portion may be bent in a radial direction of the electrode assembly, and the bending point may be spaced apart from the axial end of the insulation layer. At least a portion of the uncoated portion may be used as an electrode tab by itself.
