The invention relates to a slip ring and a rotating electric machine, which can reduce the wear amount of a brush. A slip surface of a slip ring (5) attached to a rotor part (1) of a rotating electrical machine is covered with a covering body that is formed of a metal that is smoother than the main body of the slip ring and that has a lower electrical resistance and/or volume resistivity. 本发明涉及集电环以及旋转电机，能够降低刷的磨损量。安装于旋转电机的转子部(1)的集电环(5)的滑动面由包覆体包覆，该包覆体由比该集电环的主体平滑、且电阻以及/或者体积电阻率低的金属形成。
