A PTC device which is a secondary protection device is provided on the protection circuit board, and is installed in electrical connection with an electrode terminal of a bare cell of the secondary battery.

Due to such a structural configuration of the PTC device, formation of an electrode lead is excluded for electrical connection with the bare cell on the protection circuit board. Consequently, a pattern-forming area which is designed on the protection circuit board increases.
