Zusammenfassung:	Disclosed is a secondary battery. The secondary battery is a case including an electrode assembly and a storage part for storing the electrode assembly, wherein the width of the central part along one side of the storage part is narrower than the width of both end parts of the storage part. According to the present invention, a secondary battery with high packing rates and high density can be provided, and the tearing of a raw material during a molding process of the case for storing the electrode assembly or a molding failure due to stress concentration such as the thickness difference, can be removed. 본 발명에서는 이차전지가 개시된다. 상기 이차전지는, 전극 조립체와, 전극 조립체를 수용하는 수용부를 포함하는 케이스로서, 수용부의 일 변부 방향을 따라 중앙부의 폭이 일단부 및 타단부의 폭 보다 좁은 케이스를 포함한다. 본 발명에 의하면, 높은 패킹율을 갖는 고밀도의 이차전지가 제공될 수 있고, 전극 조립체를 수용하는 케이스의 성형에서 원소재의 찢어짐이나 두께 편차와 같은 응력 집중에 기한 성형 불량을 제거할 수 있는 이차전지가 제공될 수 있다.
