Beschreibung
Zusammenfassung:	A secondary battery according to an embodiment of the present invention includes: an electrode assembly in the form of a jelly roll in which a positive electrode, a negative electrode, and a separator are wound; a battery can which accommodates the electrode assembly and has an open top; a cap assembly coupled to the open top of the battery can; and a temperature measuring member accommodated in the battery can together with the electrode assembly. One end of the temperature measuring member is positioned at the winding center of the electrode assembly, and the other end of the temperature measuring member passes between the battery can and the cap assembly and is exposed to the outside. 본 발명의 일 실시예에 따른 이차 전지는, 양극, 음극 및 분리막이 권취된 젤리롤 형태의 전극 조립체; 상기 전극 조립체가 수납되고, 상부가 개방된 전지 캔; 상기 전지 캔의 개방된 상부에 결합되는 캡 조립체; 및 상기 전극 조립체와 함께 상기 전지 캔에 수납되는 온도 측정 부재를 포함한다. 상기 온도 측정 부재의 일 단부는 상기 전극 조립체의 권취 중심에 위치하고, 상기 온도 측정 부재의 타 단부는 상기 전지 캔과 상기 캡 조립체 사이를 통과하여 외부로 노출된다.
