Disclosed are an electrode assembly, a battery, and a battery pack and a vehicle comprising same. At least one of a first electrode and a second electrode of the electrode assembly includes, at a long side end portion thereof, a non-coated portion exposed to the outside of a separator along the longitudinal direction of the electrode assembly, and at least a portion of the non-coated portion is bent in a radial direction of the electrode assembly to form a bent surface, and the bent surface may include a region in which the number of overlapping layers of the non-coated portion is maintained at a reference number of sheets along the radial direction. A welding region of a current collecting plate, which is welded to the bent surface, may overlap the region in which the number of overlapping layers of the non-coated region is maintained at the reference number of sheets.
