A current detection device, a power supply system and a method for detecting electric current is disclosed as including an electric conductor 10 which has first, second and third conductor components 11, 12, 13 extending from a diverging point O in three orientations with a given angle with respect to one another, first and second magnet-electric transducer elements 21, 22 located at both sides of the first conductor component in positions equally spaced from the first conductor component and in the vicinity of the diverging point, and a calculation processor circuit responsive to a differential value between first and second electric signals produced by the first and second transducer elements for thereby detecting electric current flowing through the first conductor component.
