description Various embodiments of the present invention relate to a secondary battery, and the objective of the present invention is to provide a secondary battery, which has drop-impact resistance, by providing an electrode assembly having a relatively thick inner circumferential and a relatively thin outer circumferential tab. To this end, disclosed is a secondary battery, which comprises an electrode assembly comprising: an anode plate having an inner circumferential tab formed at a wound front end thereof; a separator covering the anode plate; and a cathode plate having an outer circumferential tab formed at a wound distal end thereof.
