A secondary battery includes an electrode assembly having a positive electrode, a negative electrode and a separator, and a case containing the electrode assembly therein. A cap assembly is attached to the case and has a positive electrode terminal and a negative electrode terminal. The positive and the negative electrodes have non-active material portions with no active material, and the positive and the negative electrode terminals are respectively electrically connected to the non-active material portions of the positive and the negative electrodes. A width of the electrode assembly W<SUB>1 </SUB>is greater than a width of the positive and negative electrode non-active material portions W<SUB>2</SUB>.
