A rotating electric machine includes an armature that has an armature winding of multiple phases. The armature winding is configured by a conductor being wound. The conductor is configured by a plurality of wires being covered by an insulation coating in a state in which the plurality of wires are bundled. Each of the plurality of wires includes a conductor body configured to permit flow of a current, and a fusion layer that covers a surface of the conductor body. The fusion layer is configured to be thinner than the insulation coating. In the state in which the plurality of wires are bundled, fusion layers of the plurality of wires are fused and in contact with one another.
