Abstract
An electrode lead for electrically connecting an electrode assembly provided inside a case of a secondary battery with the outside of the case, according to the present invention, comprises: an inner lead which is inserted between sealing parts of the case and to which an electrode tab of the electrode assembly is attached, and which has a gas flow path so as to allow gas to flow between the inside and the outside of the case; and an external lead which is insertably disposed in the gas flow path, is electrically connected with the inner lead when inserted into the gas flow path, seals one end of the gas flow path, and is separated from the gas flow path so as to cut off electrical connection with the inner lead when the pressure of the gas flowing into the gas flow path is greater than or equal to the predetermined pressure.
