Abstract
A current detection device includes: a first conductor providing a part of a current path between a first inverter and a first rotary electric machine; a second conductor providing a part of a current path between a second inverter and a second rotary electric machine; a third conductor providing a part of a current path between a DC power supply and a converter; and first to third elements respectively arranged to face the first to third conductors. Each of the first to third elements is configured to detect a magnetic flux generated by an electric current flowing through a corresponding conductor in a coreless manner. A maximum value of the electric current in the second conductor is smaller than maximum values of the electric current in the first and third conductors. The second conductor is arranged between the first conductor and the third conductor in a predetermined direction.
