Abstract
In a rotary electric machine, a first pole core body and a second pole core body are produced using solid cores, and first slits are formed on outer circumferential surfaces of a first boss portion and a second boss portion at a uniform pitch in a circumferential direction so as to have groove directions oriented in an axial direction to disrupt pathways of eddy currents that flow on the outer circumferential surfaces of the first boss portion and the second boss portion.
