A direct current short circuit protection device includes a fuse that includes a bus bar and cuts off the bus bar in response to an ignition signal, a first current detector that includes a first resistor and detects a current flowing through the bus bar, a second current detector that includes a second resistor and detects the current flowing through the bus bar, and a disconnection control circuit that outputs the ignition signal to the fuse based on a first detection signal output from the first current detector and a second detection signal output from the second current detector, wherein the first resistor and the second resistor are integrated with the bus bar, and a current having a same magnitude as the current flowing through the bus bar flows in the first resistor and the second resistor, and the first resistor and second resistor have resistance values different from each other.
