PROBLEM TO BE SOLVED: To provide the manufacture of rotor in a simple way for a dynamo-electric machine which suppresses a coil conductor from being deformed due to centrifugal force, and prevent the generation of rare short circuit and grounding. SOLUTION: An upper coil conductor 5 involves a coil edge 5a inserted in a slot, and a set of coil ends 5b, 5c mounted continuously from both ends of the coil edge 5a and bent at roughly right angles at a jointed part to the coil edge 5a. The set of coil ends 5b, 5c are mounted, inclined at a prescribed angle with respect to the side opposite to each other in the circumferential direction around the coil edge 5a. The upper coil conductor 5 is formed into a roughly U-shape by bending both the coil ends 5b, 5c into roughly right angles to the coil edge 5a at a jointed part of the coil edge 5a to both the coil end parts 5b, 5c of a coil material 50 formed into a prescribed shape after both the coil ends 5b, 5c are inclined on the identical plane by prescribed anglesθ1 ,θ2 respectively to the coil edge 5a.
