    摘要： A connecting element for a secondary battery is installed on a path of current flowing through a secondary battery to electrically connect components and includes a first metal plate having a first protrusion formed to protrude at one side end thereof from the center portion of the thickness direction thereof, a second metal plate located spaced apart from the first metal plate with a gap being formed therebetween and having a second protrusion formed to protrude at one side end thereof from the center portion of the thickness direction thereof and face the first protrusion, and an alloy bridge made of alloy material having a melting point lower than those of the first metal plate and the second metal plate and formed to fill the gap. The connecting element may ensure the safety of the secondary battery in use, minimize the increase of resistance caused by applying the connecting element, and be rapidly broken even though the connecting element is applied as a part with a relatively great thickness.
