A battery pack includes a plurality of battery modules, each having at least one unit cell, a case for accommodating the unit cell and a bus bar electrically connected to the unit cell, and a connecting bar for connecting battery modules adjacent to each other among the plurality of battery modules, wherein at least one of the connecting bars includes a first metal plate, a second metal plate spaced apart from the first metal plate, and a metal bridge configured to connect the first metal plate and the second metal plate and having a lower melting point than the metal plate. In this configuration, if an overcurrent flows at the battery pack, the connecting bar is easily broken, thereby ensuring safety of the battery pack in use.
