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.

Abstract: The present disclosure provides an inductive element capable of lowering a Q-value. An inductive element includes a first cover and a second cover covering an annular core, and a first winding and a second winding wound around a region of the core, the first cover and the second cover. The first cover covers a part of an inner circumferential surface of the core, a part of an outer circumferential surface and an end surface on one end side in an axial direction. The second cover covers a part of the inner circumferential surface of the core, a part of the outer circumferential surface an end surface on the other end side in the axial direction.
