Abstract
A electric rotating machine includes a rotor winding constituting a part of a rotor, a conductor provided in a center portion in a radial direction of a rotor body for supplying electricity to the rotor winding from the outside, a leader drawn from the conductor to an outside diameter side, and a connecting line constructed by stacking a plurality of conductor plates to electrically connect the rotor winding and the leader. The connecting line consists of a radial direction linear portion which is straight in the radial direction on the leader side, and a bending portion which branches into two routes toward opposite directions to each other in a rotor shaft direction from the radial direction linear portion and has a linear portion formed at a part of the bending portion. The linear portion of the bending portion is joined to a bottom surface of the rotor winding.
