Zusammenfassung:	A technical object to be solved according to the present disclosure is to provide a secondary battery which has reduced electrical resistance by directly connecting an electrode assembly to a can and/or a terminal without lead tabs and also has an increased battery capacity by removing lead tabs. To this end, the present disclosure provides a secondary battery comprising: a can; an electrode assembly accommodated in the can and including a first uncoated portion extending in a first direction and a second uncoated portion extending in a second direction opposite to the first direction; a first current collector plate electrically connected to the first uncoated portion of the electrode assembly; a first terminal portion coupled to the can and electrically connected to the first current collector plate; and a second terminal portion coupled to the can and electrically connected to the second uncoated portion of the electrode assembly.
