An electric compressor includes a compression member configured to compress fluid, an electric motor configured to drive the compression member, an inverter configured to drive the electric motor, a housing accommodating the compression member, the electric motor, and the inverter, and a soundproof cover covering the housing. The housing includes a plurality of housing elements. The soundproof cover has a facing portion facing the housing. The facing portion has a groove that surrounds a boundary between two of the housing elements that are adjacent to each other and is distant from the boundary.

A seal member includes pushing projections that project from a seal body toward at a groove inner-side circumferential surface and are arranged at intervals in a circumferential direction of the seal body. The pushing projections push the seal body against the groove inner-side circumferential surface and a groove outer-side circumferential surface between the groove inner-side circumferential surface and the groove outer-side circumferential surface. This reduces the gap between the groove outer-side circumferential surface and the seal member in the seal accommodating groove. Thus, salt water is unlikely to collect in the gap between the groove outer-side circumferential surface of the seal accommodating groove and the seal member. This improves the corrosion resistance of the housing and the seal member.
