Electrode assembly and secondary battery using the same

A coupling structure for electrode tabs (210,220) of a stacked-type secondary battery and a secondary battery using the same are disclosed. A coupling structure for electrode tabs of a secondary battery comprises: an electrode assembly formed by stacking a plurality of electrode plates (110,120); a tab portion (200) formed by stacking electrode tabs (210,220) protruding from one side of the electrode plates of the electrode assembly; and a coupling member (300) that surrounds an outer surface of the tab portion (200) so that the electrode tabs (210,220) of the tab portion (200) are connected to one another.
