Summary:A secondary battery which has a case, an electrode assembly which is housed in the case and includes a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode, a cap assembly which is assembled with the case to close and seal the electrode assembly and to lead an electric current, and a positive current collecting plate and a negative current collecting plate that are electrically connected with the electrode assembly and that face each other. The negative electrode includes an uncoated region which is not coated with an active material at the end of the negative electrode, and the uncoated region is electrically connected with a negative current collecting plate whose surface is treated with a metal different from the metal of the negative electrode.
