<p>Provided is an inverter-integrated electric compressor configured such that suction refrigerant collects only in the vicinity of a switching element module (105) which is the main heat generating source for an inverter unit (101), by the disposal of a suction refrigerant path (61), wherein suction refrigerant (30) collects and flows, only in the vicinity of the switching element module (105) which is the main heat generating source for the inverter unit (101). The inverter-integrated electric compressor can effectively cool the inverter unit with the suction refrigerant without adjusting the operating conditions of the refrigeration cycle.</p>
