Abstract
A secondary battery includes a case in which an opening is formed. An electrode assembly is accommodated in the case, with the electrode assembly including an electrode. An electrode tab is connected to the electrode and protrudes outwardly from the electrode assembly, a cover covers the opening in the case to seal the electrode assembly from outside. An insulating member is placed on a surface of the electrode tab coupled to the side of the case, with the insulating member being positioned between the electrode assembly and the electrode tab.
