Electric compressor

The invention aims to suppress an increase in the size of a housing in the diameter direction of an inverter-integrated electric compressor while assuring cooling performance during power switching of insulated gate bipolar transistors (IGBTs) and the like. [Solution] A housing (2) has a partition wall (6) that separates a first space (S1), wherein a compression mechanism and an electric motor are accommodated, and an intake refrigerant flows therethrough, and a second space (S2), wherein an inverter (5) that includes IGBTs (Q1-Q6) is accommodated, from each other. The partition wall (6) has a bulge section (22) that protrudes toward the first space (S1) side. The IGBTs (Q1-Q6) are arranged in thermal contact with inner surfaces (22a, 22b) of the bulge section (22). 在逆变器体型电动压缩机中，确保对于IGBT等的功率开关的冷却性能，并抑制外壳的直径方向的体积增大。外壳(2)具有分隔壁(6)，其分隔收纳压缩机构和电动机并流过吸入制冷剂的第空间(S1)和收纳包含IGBT(Q1～Q6)的逆变器(5)的第二空间(S2)。分隔壁(6)具有向第空间(S1)侧突出的凸起部(22)。IGBT(Q1～Q6)与凸起部(22)的内表面(22a、22b)以热接触的方式配置。
