Zusammenfassung:	Disclosed is a secondary battery. The secondary battery comprises: an electrode assembly; a battery case accommodating the electrode assembly and an electrolyte at the same time; a lead terminal extended across the battery case from a coupling part of the electrode assembly, and drawn outside the battery case; and an adhesive layer showing adhesion according to a reaction with the electrolyte. According to the present invention, provided is a secondary battery with an improved structure to prevent internal short circuit and improve safety. 본 발명에서는 이차전지가 개시된다. 상기 이차전지는, 전극 조립체와, 전극 조립체와 함께 전해액을 수용하는 전지 케이스와, 전극 조립체와의 결합부로부터 전지 케이스를 가로질러 연장되며, 전지 케이스의 외부로 인출되는 리드 단자와, 리드 단자 상에 형성된 것으로, 전해액과의 반응에 따라 점착성을 나타내는 점착층을 포함한다. 본 발명에 의하면, 내부 단락이 방지되고 안전성이 향상되도록 구조가 개선된 이차전지가 제공된다.
