Abstract: A rotating electric machine includes a pair of electric conductors for forming a coil and a weld. Each of the electric conductors has an end portion with an end surface. The weld is formed between the end portions of the electric conductors at the end surfaces of the end portions. Moreover, the end portions of the electric conductors are arranged so that parts of the end portions of the electric conductors adjoin each other. At least one of the end portions of the electric conductors has at least one slit formed therein to divide the end surface of the end portion into a plurality of sections. The weld is formed to cover, at least, the adjoining parts of the end portions of the electric conductors and the at least one slit.

Abstract: A rotating electric machine includes a weld formed by welding end portions of a pair of electric conductors for forming a coil and a weld-insulating member that covers, at least, a surface of the weld. The weld has an uneven portion formed on at least part of the surface thereof. The uneven portion is constituted of a plurality of annular recesses and a plurality of annular protrusions. The annular recesses are formed alternately and continuously with the annular protrusions.
