description	An embodiment of the present invention relates to a cylindrical secondary battery comprising: a cylindrical can having a bottom surface and a side portion extending from the bottom surface, wherein one end of the side portion is open to form an opening; an electrode assembly accommodated in the can; and a cap assembly including a gasket which is inserted into the can in a state in which the electrode assembly is inserted in the can to come in contact with the electrode assembly, and a cap plate which is disposed on the gasket and is electrically connected to the electrode assembly, wherein the can has, at the edge of the opening, a curling portion which presses the gasket to bring the gasket in contact with the cap plate. The sealing force of the secondary battery can be enhanced. 본 발명의 실시예는 원통형 이차전지에 관한 것으로, 바닥면과, 상기 바닥면으로부터 연장된 측부를 구비하며, 상기 측부의 일단이 개구되어 개구부를 형성하는 원통형 캔; 상기 캔에 수용되는 전극 조립체; 및 상기 캔에 상기 전극 조립체가 삽입된 상태에서 상기 캔에 삽입되어 상기 전극 조립체에 접촉되는 가스켓과, 상기 가스켓 상에 배치되어 상기 전극 조립체와 전기적으로 연결되는 캡 플레이트를 구비한 캡 어셈블리를 포함하고, 상기 캔은 상기 개구부 가장자리에 상기 가스켓을 가압하여 상기 캡 플레이트에 접촉시키는 컬링부가 형성된 것을 특징으로 한다.
