A switch box includes a relay transistor circuit connecting a pair of batteries in parallel, and an breaker circuit that breaks the relay transistor circuit when a sign of a potential difference between a potential of at least one of the pair of batteries connected to the relay transistor circuit and a predetermined reference potential is reversed with respect to the sign of the potential difference in which the batteries are correctly connected.
