PROBLEM TO BE SOLVED: To provide an inexpensive manufacturing method of a rotor core of an embedded magnet type rotary electric machine, which achieves high output and low cost, and to provide the rotor core manufactured by the manufacturing method, a rotor using the rotor core and the embedded magnet type rotary electric machine having the rotor. SOLUTION: The rotor core of the embedded magnet type rotary electric machine is composed by laminating a plate-like member of a compound magnetic material, which has a ferromagnetic part and a feebly magnetic part in the same member. The compound magnetic material is previously worked in a shape set as the ferromagnetic material and is laminated. Then a setting part is heated to form the feebly magnetic part.
