Abstract: A vehicle electric compressor includes a compression part, an electric motor, and an inverter device. The inverter device includes a noise reduction unit that includes a common mode choke coil. The common mode choke coil includes a core, a first winding wire, a second winding wire, and an electrical conductor that covers the core. The electrical conductor has a first insulation layer and a second insulation layer. The first insulation layer, the electrical conductor, and the second insulation layer form a laminated body including a loop-shaped portion that covers the core and a joint portion.
