Beschreibung
Zusammenfassung:	In an electric power steering apparatus including a capacitor for smoothing out the voltage of a battery and a relay including a relay contact disposed at a place upstream of the capacitor, a path is provided for directly conducting a terminal voltage of the capacitor from a downstream side of the relay contact to a system power supply that generates a source voltage for a control system including a controller and the like, so that the system power supply and the control system that is supplied therefrom with electric power for control purpose are utilized as a discharge circuit. Thus is obtained a simplified configuration of circuit responsible for discharging the capacitor.
