A secondary battery is disclosed. The secondary battery includes an electrode assembly which comprises a first electrode and a second electrode; an electrode terminal which is electrically connected to the electrode assembly; a case which accommodates the electrode assembly; a cap plate which is installed in an opening of the case to seal the case, and has a vent hole through which internal pressure of the case is discharged, and a vent plate to seal the vent hole; and a short-circuit member which has one end electrically connected to the electrode assembly and the other end extended toward the vent hole in the case. The short-circuit member is deformed when the internal pressure is discharged, so it can be drawn from the vent hole to the outside. |
