An object of the present invention is to provide an electric rotating machine and a method of connecting feeding lead wires thereto, which can increase the resistance to centrifugal forces of the lead wire without controlling the hardness of the lead wire by post-processing such as cold pressing and suppress plastic deformation of the joint between the lead wire and the joint conductor. To materialize the above object, the feeding lead wire in accordance with the present invention comprises a first part connected to a joint conductor having a first thickness, a second part having a second thickness that is thinner than said first thickness, and a third part that is formed between said first and second parts and has a thickness changing from said first thickness to said second thickness. The first part of the feeding lead wire is welded to the joint conductor by electron beams or brazed to the joint conductor while the feeding lead wire is being cooled.
