Abstract
A drive device includes a rotating electric machine, a substrate, a first drive element, a second drive element, a first extension line, and a second extension line. The 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. 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. In such manner, variation of wiring lengths from an electric power supply region among different phases is reduced.
