A power module (3) includes a multilayer circuit board (30), and a first three-phase inverter (6) and a second three-phase inverter (7), which are mounted on the multilayer circuit board (30) so as to be stacked each other. A positive-electrode-side power source conductive trace (71) of the first three-phase inverter (6) and a negative-electrode-side power source conductive trace (102) of the second three-phase inverter (7) are disposed so as to at least partially face each other in a stacking direction of the multilayer circuit board (30), such that currents respectively flow through the power source conductive traces (71, 102) in opposite directions in a facing section. A negative-electrode-side power source conductive trace (72) of the first three-phase inverter (6) and a positive-electrode-side power source conductive trace (101) of the second three-phase inverter (7) are disposed so as to at least partially face each other in the stacking direction of the multilayer circuit board (30), such that currents respectively flow through the power source conductive traces (72, 101) in opposite directions in a facing section.
