Electric compressor for vehicle, and method for manufacturing electric compressor for vehicle

An electric compressor for a vehicle comprising:

• a compressor case made of a conductive metal material and having a pipe shape, the compressor case housing a compression mechanism which draws, compresses and discharges refrigerant, and an electric motor which drives the compression mechanism;
• an inverter circuit that drives the electric motor with electric current;
• an inverter case made of a conductive metal material and arranged on one side of the compressor case in an axial direction, the inverter case having a storage part that houses the inverter circuit and an opening open on one side in the axial direction;
• a lid made of a conductive metal material, the lid closing the opening of the inverter case;
• a seal component interposed between the inverter case and the lid to seal a gap between the inverter case and the lid;
• and
• a conductive component which transmits an electromagnetic wave noise, that is propagating from the inverter circuit to the inverter case when the inverter circuit provides the electric current flowing through the electric motor, from the inverter case to at least one of the compressor case and the lid
• wherein,
• the seal component is made of material having electrical insulation properties, and has a ring shape surrounding the opening,
• the conductive component has a ring shape surrounding the opening, and is arranged at an inner side or an outer side of the seal component to achieve electrical connection between the inverter case and the lid,
• the seal component is joined to the conductive component, and
• the electromagnetic wave noise from the inverter case is transmitted from the conductive component to the lid.
