<p>An embodiment of the present invention provides an electrode assembly (10) and a secondary battery using the same that are capable of omitting a process to attaching an additional electrode lead by increasing the thickness of an outermost substrate among electrode plates and the size of an electrode tab to use electrodes tabs of internal substrates as an electrode lead while tying the electrode tabs of the internal substrates. The electrode assembly (10) according to the embodiment of the present invention includes: a first electrode plate with a first electrode tab extending to one side; a second electrode plate with a second electrode tab extending to the other side not to be overlapped with the first electrode tab; and a separator interposed between the first electrode plate and the second electrode plate, wherein a first outermost electrode tab (40) of a pair of first outermost electrodes (41) and a second outermost electrode tab (50) of a pair of outermost electrode plates (51) that are positioned at the outermost side between the first electrode plate and the second electrode plate are larger and thicker than a plurality of first intermediate electrode tabs and second intermediate electrode tabs that are positioned in the middle of the first electrode plate and the second electrode plate to cover the plurality of first intermediate electrode tabs and second intermediate electrode tabs.</p> |
