The present invention provides a rotary electric machine that can achieve prompt restarting and that can also reduce eddy current loss by reducing eddy currents that flow through an outer circumferential surface of a boss portion of a pole core due to the changes in flux in field magnetic flux build-up during starting to enable prompt field magnetic flux build-up in response to a restarting command. In a rotary electric machine according to the present invention, a first pole core body (17) and a second pole core body (21) are produced using solid cores, and first slits (25) are formed on outer circumferential surfaces of a first boss portion (18) and a second boss portion (22) 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 (18) and the second boss portion (22). |
