Abstract
An electric leakage detecting apparatus, in an electric leakage detecting apparatus which is insulated from a chassis ground and detects electric leakages of a battery, is provided with: a voltage dividing circuit that divides an output voltage of the battery; an electric leakage determining circuit provided at a rear stage of the voltage dividing circuit, that determines the presence of an electric leakage based on a voltage detected by a circuit that respectively connects to a positive electrode side insulation resistance or a negative electrode side insulation resistance of the battery; and a dark current inhibit circuit in which a switch and a resistance are connected in parallel, that is inserted between at least either one of wiring that connects a positive terminal of the battery and the voltage dividing circuit, and wiring that connects a negative terminal of the battery and the voltage dividing circuit.
