1. A current interrupt device comprising:
a first connection part having one surface on which an inclined surface is formed;
a second connection part having one surface on which an inclined surface having a shape corresponding to the inclined surface of the first connection part is formed;
a first fixing part disposed on an outer portion of the first connection part so that the first connection part is configured to be coupled to a portion of a circumferential portion of a first secondary battery; and
a second fixing part disposed on an outer portion of the second connection part so that the second connection part is configured to be coupled to a portion of a circumferential portion of a second secondary battery,
wherein the inclined surface of the first connection part and the inclined surface of the second connection part contact each other to form a contact interface,
the first connection part and the second connection part are electrically connected to each other,
the inclined surface of the first connection part and the inclined surface of the second connection part are configured to be dislocated with respect to each other at the contact interface to interrupt electrical connection between the first connection part and the second connection part,
the first fixing part forms a corner with and extends substantially perpendicular to a remainder of the first connection part, and
the second fixing part forms a corner with and extends substantially perpendicular to a remainder of the second connection part.
