PROBLEM TO BE SOLVED: To obtain a rotor for a permanent magnet-type rotary electric machine, which has simple structure and can detect its rotational position accurately, and a method of manufacturing the rotor for the permanent magnet-type rotary electric machine. SOLUTION: In this rotor for the permanent magnet-type rotary electric machine, which includes a rotating shaft, a rotor core 2, a plurality of permanent magnets 3 arranged around the rotor core 2 and a singular or plural conductive circuits constituted to surround the environs or the peripheral side of the plural permanent magnets 3 and which detects the rotational position of the rotor 1 from the difference of inductance made by an induced current flowing in the conductive circuit, the permanent magnets 3 and the conductive circuits are constituted of conductive members 4 molded integrally.
