PROBLEM TO BE SOLVED: To provide a magnetic bearing device, capable of considerably reducing the generation of an eddy current without using laminated steel plates, thereby reducing heat generation and eddy current loss of a rotor by a large margin and making the rotor into a solid to facilitate high-speed rotation. SOLUTION: In this homopolar-type magnetic bearing device, where the tooth end parts 2a of a stator 2 surrounding the rotor 1 are arranged axially adjacent to constitute N-poles and S-poles, the adjacent N-poles and the adjacent S-poles are connected integrally to each other in a circumferential direction, or the adjacent N-poles and the adjacent S-poles are circumferentially connected to each other by magnetic substances of different materials, or the adjacent N-poles and the adjacent S-poles are respectively projected in the circumferential direction to be adjacent to each other with a slight clearance.
