  • the present invention is applied to the motor-driven compressor 10, which is mounted on a hybrid automobile and used in a vehicle air conditioner.
  • the present invention may be applied to a motor-driven compressor that is used in a vehicle air conditioner mounted on an automobile driven only by gasoline or on an electric car.
  • a motor-driven compressor includes a connector receiving portion provided on the outer surface of a housing.
  • a wiring connection portion is provided in the connector receiving portion and supplies electricity from an external power source to a motor drive circuit.
  • An insulating member provided inside the connector receiving portion insulates the wiring connection portion and the connector receiving portion from each other.
  • An electrical wire is arranged between the inner surface of the connector receiving portion and the insulating member. The electric wire is used for a purpose other than supply of electricity to the motor drive circuit.
  • a recess is formed in at least one of the inner surface of the connector receiving portion and the outer surface of the insulating member. The recess forms a wiring space, in which the electrical wire is arranged, between the connector receiving portion and the insulating member.
