Provided are a jelly-roll type electrode assembly that is improved in battery reliance and battery stability when external shocks are applied to a battery, and a lithium secondary battery comprising the same. The jelly-roll type electrode assembly comprises: a first electrode plate(110); a second electrode plate(120); and a separator(130) which is interposed between the first electrode plate(110) and the second electrode plate(120) and insulates the electrode plates from each other and of which a protrusion part upper than the first and second electrode plates(110,120) is longer than the lower protrusion part by 0.3-1.0mm. |
