PROBLEM TO BE SOLVED: To provide a rotor for a dynamo-electric machine which is possible of high-speed revolution by reducing the tensile force added to fragile material at high-speed revolution, in a rotor which is made by integrating ductile material and fragile material. SOLUTION: In the rotor of the dynamo-electric machine which is made by arranging a member consisting of fragile material and a member consisting of ductile material on a rotational plane, a contact part between the member consisting of the fragile material and the member consisting of ductile material is made in such form that the shifting in the rotating shaft direction of the member consisting of ductile material can be regulated by the arrangement of the member consisting of fragile material, and the member consisting of fragile material and the member consisting of ductile material are put in contact form thereby being retained by their form. The contact parts of the member consisting of fragile material and the member consisting of ductile material are coupled with each other by low elastic-modulus adhesive which is transformable at addition of centrifugal force.
