To restrain heat dissipating grease from adhering to a seal member.SOLUTION: An electric compressor 10 comprises a housing 11, and an inverter case 32 housing an inverter. The inverter case 32 is arranged in such a manner that a second wall part 60 and a first wall part 50 are opposed to each other. The first wall part 50 and the second wall part 60 comprise joint surfaces 52 and 62 opposed to each other, respectively. The electric compressor 10 comprises an annular seal member 71 and a heat dissipating grease 72. The seal member 71 and the heat dissipating grease 72 are arranged between the first wall part 50 and the second wall part 60. The joint surfaces 52 and 62 comprise heat dissipating surfaces 54 and 64 between which a face-to-face distance d2 is shorter than a face-to-face distance d1 between seal surfaces 53 and 63. The first wall part 50 comprises a groove 55 between the seal surface 53 in contact with the seal member 71 and the heat dissipating surface 54.SELECTED DRAWING: Figure 3 【課題】シール部材に放熱グリスが付着することを抑制すること。【解決手段】電動圧縮機１０は、ハウジング１１と、インバータを収容しているインバータケース３２と、を備える。インバータケース３２は、第２壁部６０と第１壁部５０とが互いに向かい合うように配置されている。第１壁部５０、及び、第２壁部６０は、それぞれ、互いに向かい合う接合面５２，６２を備える。電動圧縮機１０は、環状のシール部材７１と、放熱グリス７２と、を備える。シール部材７１、及び、放熱グリス７２は、第１壁部５０と第２壁部６０との間に配置されている。接合面５２，６２は、シール面５３，６３同士の面間距離ｄ１よりも面間距離ｄ２の短い放熱面５４，６４を備える。第１壁部５０は、シール部材７１に接するシール面５３と、放熱面５４との間に溝５５を備える。【選択図】図３
