PROBLEM TO BE SOLVED: To provide a high revolution, high output, and low-cost rotating machine by dispersing the magnetic flux of a rotor with a built-in magnet and reducing torque ripples, and securing smooth rotation of the rotor. SOLUTION: A rotor 11 with a built-in magnet of a rotating machine is composed of a plurality of sleeves 31 and 32, which have plural pieces of permanent magnets 20 which are built in so that they form magnetic poles being alternately different in polarity in the rotational direction, and a shaft 12 which supports these in stacked conditions. The divided sleeves 31 and 32 are coupled integrally with each other, by stacking and fitting them on the shaft in the axial direction, in the condition that the several magnetic poles are shifted in the rotational direction.
