Claim Text:
1. A drive device comprising: a rotating electric machine including a stator with a first winding group and a second winding group wound on the stator in at least three phases, a rotor rotatably disposed relative to the stator, and a shaft rotating with the rotor; a substrate disposed on one axial end of the rotating electric machine; a first drive element (i) arranged on one surface of the substrate in a first region and (ii) constituting a first inverter that switches a power supply to the first winding group; a second drive element (i) arranged on a same surface of the substrate as the first drive element in a second region and (ii) constituting a second inverter that switches a power supply to the second winding group, the second region being symmetric to the first region relative to a shaft of the rotating electric machine; a first extension line extending from each of the at least three phases of the first winding group to be connected to the substrate; and a second extension line extending from each of the at least three phases of the second winding group to be connected to the substrate, wherein the first extension line and the first drive element, as well as the second extension line and the second drive element have respectively reversed phase orders in an arrangement of the phase orders from an end close to a reference position toward an other end of the arrangement.
