PROBLEM TO BE SOLVED: To provide a rotor capable of maintaining a strength even in the case where stirring is performed using friction stirring, and a manufacturing method for the rotor.SOLUTION: A rotor comprises: a plurality of rod-shaped conductors; a first end ring of which one face communicates to one end of the plurality of conductors and the at least surface at a side opposite to the side communicating to the plurality of conductors is stirred by friction stirring; a second end ring which is disc-shaped and of which one face communicates to the other end of the plurality of conductors and the at least surface at a side opposite to the side communicating to the plurality of conductors is stirred by the friction stirring; and a cylindrical core which provided between the first and second end rings, a plurality of insertion holes through which the plurality of conductors can be inserted being formed in a center axis direction in the core. At least one end ring between the first and second end rings is integrated with the plurality of conductors.SELECTED DRAWING: Figure 1 【課題】摩擦撹拌を用いて撹拌を行った場合でも強度を維持することができる回転子およびこの回転子の製造方法を提供すること。【解決手段】本発明にかかる回転子は、棒状をなす複数の導体と、円板状をなし、一方の面が複数の導体の一端に連なるとともに、少なくとも複数の導体に連なる側と反対側の表面が、摩擦撹拌により撹拌されてなる第１の端絡環と、円板状をなし、一方の面が複数の導体の他端に連なるとともに、少なくとも複数の導体に連なる側と反対側の表面が、該摩擦撹拌により撹拌されてなる第２の端絡環と、第１および第２の端絡環の間に設けられている筒状の鉄心であって、中心軸方向に沿って複数の導体をそれぞれ挿通可能な複数の挿通孔が形成された鉄心と、を備え、第１および第２の端絡環のうち少なくとも一方の端絡環が、複数の導体と一体化されている。【選択図】図１
