Abstract
An on-vehicle motor-driven compressor includes an inverter device having a noise reducer. The noise reducer includes a common mode choke coil. The common mode choke coil includes an annular core, first and second windings wound around the core, the second winding being spaced apart from and opposed to the first winding, an annular conductor that extends over the first winding and the second winding and covers the core, and an insulating layer located between an inner circumferential surface of the conductor and outer surfaces of the first winding and the second winding. The conductor is tubular and belt-shaped. The core includes an exposed portion that is not covered by the conductor. The insulating layer is tubular and belt-shaped. An entirety of the conductor is arranged within a range between opposite ends of the insulating layer.
