It comprises a detection type FET and a flip-flop that switches to a set state when the detection signal is input and outputs a current cutoff signal to the gate of the FET, and the gate of the FET closes when it receives the current cutoff signal. and a short circuit protection device for a battery pack configured to cut off supply of the output current. (2) A battery pack equipped with a short-circuit protection device according to claim 1, further comprising a remaining capacity display switch for instructing a remaining capacity display of the power source, and in conjunction with operation of the display switch, the flip-flop is brought into a reset state. The battery pack is adapted to be reset to open the gate of the FET.
