Abstract
An on-vehicle motor-driven compressor includes a compression unit, an electric motor, and an inverter device. The inverter device includes an inverter circuit and a noise reducer. The noise reducer includes a common-mode choke coil and a smoothing capacitor. The common-mode choke coil includes a loop-shaped core, a first winding wound around the core, a second winding wound around the core, the second winding being spaced apart from and opposed to the first winding, and a loop-shaped conductor that covers the core while extending over the first winding and the second winding. The core includes an exposed portion that is not covered with the conductor. Parts of the conductor that are opposed to each other between the first winding and the second winding are spaced apart from each other.
