An electric compressor comprising:
- an electric motor;
- a shaft configured to be driven by the electric motor;
- two impellers respectively provided in both ends of the shaft;
- two housings respectively accommodating the two impellers;
- and
- an intake manifold pipe configured to branch off from one intake pipe to supply a gas to each of the two housings,
- wherein each of the two housings includes an intake port which is open in a direction intersecting with an axial direction of the shaft, the intake manifold pipe being connected to the intake port, and
- wherein each of the two housings includes
- an inner surface that defines a supply flow path for guiding the gas supplied from the intake port to a leading edge of the impeller, the inner surface including an inner end wall surface that defines a side opposite to the impeller in the supply flow path, and an inner peripheral wall surface that defines an outer peripheral side of the supply flow path, and
- a guide protruding portion that protrudes toward the leading edge of the impeller from the inner end wall surface.
