At normal times other than a restarting of an engine after being idling-stopped, a voltage Va1 detected by a current detection circuit 5 when a bypass switch SW2 is turned off is acquired, and a voltage Va2 detected by the current detection circuit 5 when the bypass switch SW2 is turned on is also acquired, and an electric current I1 flowing from a battery B to a load Lo via the bypass switch SW2 is obtained on the basis of a difference between the voltage Va2 and the voltage Va1.
