While in normal operation except when restarting an engine after idling stop, a power source circuit acquires a voltage (Va1) detected by a current detection circuit (5) when turning a bypass switch (SW2) off while acquiring a voltage (Va2) detected by the current detection circuit (5) when turning a bypass switch (SW2) on, and calculates, from the difference between the voltage (Va2) and the voltage (Va1), a current (I1) that flows to a load (Lo) from a battery (B) through a bypass switch (SW2).
