Provided is a magnetic bearing device capable of facilitating manufacture of the magnetic bearing device and improving precision in production thereof while maintaining eddy current reducing effects. The magnetic bearing device 10 supporting a rotating shaft 3 with a magnetic force includes a plurality of magnetic poles 5 arranged in the circumferential direction of the rotating shaft 3. Each magnetic pole 5 includes an inner end surface 5b facing the outer surface of the rotating shaft in proximity thereto. The magnetic poles which are adjacent to each other in the circumferential direction respectively extend in the axial directions of the magnetic poles 5 to the inner end surfaces 5b of the magnetic poles so as to virtually interfere with each other in the vicinity of the outer surface of the rotating shaft. The virtual interfering portions 5a of both the magnetic poles 5 capable of interfering with each other are removed by cutting.
