Claim:
1. A circuit board for a secondary battery, which is connected to at least one of a cathode tab and an anode tab of the secondary battery, the circuit board comprising: a tab coupling portion connected to the cathode tab or the anode tab; a charging/discharging path connected to the tab coupling portion to give a path through which a charging current or a discharging current of the secondary battery flows, the charging/discharging path having at least one path cutting portion formed therein; one pair of conductive plates respectively attached to both ends of the path cutting portion, the conductive plates being at least partially bent; and a current interruption module having both ends respectively connected to the one pair of conductive plates, the current interruption module sensing a temperature of the secondary battery and interrupting a current according to the sensed temperature.
