| 2. An electric compressor comprising:
a compression mechanism which sucks, compresses and discharges fluid;
an electric motor which drives said compression mechanism;
a housing containing said compression mechanism and said electric motor; and
an inverter which drives said electric motor,
wherein an inverter case of said inverter is externally attached to an end wall of said housing in an axial direction at a
side of said compression mechanism having a discharge port, said end wall having a suction port which returns fluid to said
compression mechanism,
an intake passage which returns fluid to said suction port, wherein said suction port is provided in said inverter case, and
wherein said intake passage has a thermal binding portion which thermally binds said intake passage to said inverter, wherein
an air layer is provided between said intake passage and said end wall, and wherein said thermal binding portion has a plurality
of fins projecting into a fluid path of said intake passage, said inverter case having an end surface connected to an end
wall of said housing such that said end surface of the inverter case defines at least part of said intake passage, and said
thermal binding portion being positioned within said inverter case.
