Abstract

A current interrupt device, which may be included in a battery module, includes first and second connection parts each having one surface on which an inclined surface is formed; 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, and when an external force equal to or greater than a predetermined force is applied to the inclined surface of the first connection part or the inclined surface of the second connection part, the inclined surface of the first connection part and the inclined surface of the second connection part are dislocated with respect to each other on the contact interface to interrupt electrical connection between the first connection part and the second connection part.
