In producing a rotor for a rotating machine by bonding a rotor body and a plurality of permanent magnets to each other through a heating step and a subsequent cooling step, a rotor body having a larger coefficicient of linear thermal expansion at the cooling step has its joint surface formed by assembling of a plurality of small joint faces. Thus, it is possible to moderate a thermal stress in a brazing filler metal layer between the rotor body and each of the permanent magnets to avoid the generation of cracks in the permanent magnets having a smaller coefficient of linear thermal expansion at the cooling step and to firmly bond the rotor body and each of the permanent magnets to each other.
