    Abstract: An electric compressor includes: a compression part; an electric motor; an inverter; a housing including a plurality of housing forming members made of metal; a seal member that has an insulation property and is provided between the housing forming members adjacent to each other; and a potential equalization member that is made of metal and is in contact with both the adjacent housing forming members to equalize potentials of the adjacent housing forming members. The adjacent housing forming members include mating surfaces, respectively. An insertion hole is formed in one of the mating surfaces of the adjacent housing forming members, at a position in which the seal member is not provided. The potential equalization member includes an insertion portion inserted into the insertion hole, and a contact portion that is a plate portion extending in a gap between the mating surfaces and is in contact with both the mating surfaces.
