It is an object to provide an integrated-inverter electric compressor in which variations in sealing performance hardly occur, thus reliably enhancing the waterproofing performance of an inverter accommodating section. An integrated-inverter electric compressor in which an inverter accommodating section (9) is provided on the periphery of a housing, an inverter that supplies driving power to an electric motor is installed in the inverter accommodating section (9), and its opening (10) is tightly sealed with a cover (13) is configured such that a groove (16) in which a liquid sealant (20) is to be filled is provided in a flange (11) around the opening (10) of the inverter accommodating section (9); the liquid sealant (20) filled in the groove (16) is cured to tightly seal a joint surface between the flange (11) and the cover (13); and when the width of a joint surface (17) formed at the inner periphery of the groove (16) in the flange (11) is L1 and the width of a joint surface (18) formed at the outer periphery of the groove (16) is L2, L1<L2 holds.
