Abstract
In a rotary electric machine, a conductive member surrounds a shaft and a plurality of permanent magnets provided on an outer peripheral portion of the shaft as a whole, and a holding member surrounds the shaft, the plurality of permanent magnets, and the conductive member as a whole. A conductivity of the conductive member is higher than a conductivity of the permanent magnet. The conductive member includes first and second opposing portions that oppose each other via a gap in a circumferential direction. An inter-opposing portion region existing between the first and second opposing portions is positioned within a circumferential direction range of an inter-magnet region existing between permanent magnets that are adjacent to each other in the circumferential direction.
