Abstract: The present invention relates to a sealing apparatus sealing a sealing part of a battery case at which an electrode lead coupled to an electrode assembly is disposed. The sealing apparatus comprises: a thermal fusion member applying heat and a pressure to the sealing part of the battery case, at which the electrode lead is disposed, to seal the sealing part; and a temperature rising prevention member supported on a front end of the electrode lead to cool the sealing part through the electrode lead, thereby preventing the sealing part from increasing in temperature.
