To provide a magnetic bearing type pump to restrain generation of an eddy current on a shaft, to minimize heating of the shaft and to improve in efficiency.

An electromagnetic target to constitute a target of an electromagnet to constitute a radial magnetic bearing part, a radial sensor target to constitute a target of a coil to detect displacement of the shaft in the neighbourhood of the magnetic bearing part and a collar between the electromagnet target and the radial sensor target are constituted of a laminated steel plate. As a result, generation of the eddy current generated on the shaft due to a magnetic field generated on the magnetic bearing part is reduced.
