In an electric compressor, an inverter case of an inverter is externally
attached to an end wall of a housing in an axial direction on the side of
a suction port to a compression mechanism. An intake passage for leading
fluid returned from the outside into the suction port is provided in the
inverter case. The intake passage has a thermal binding portion for
thermally binding the intake passage to the inverter. According to the
above structure, an exclusive part in the housing is eliminated even
though the inverter is installed in the electric compressor, and the
inverter is cooled efficiently.
