摘要
A centrifugal pump includes a rotating shaft, a pump substrate, a housing and an impeller. The pump substrate has a driving unit configured to rotate the rotating shaft. The housing has an inlet and an outlet and forms a pump chamber with the pump substrate. A body fluid sucked from the inlet flows through the pump chamber. The impeller is housed in the pump chamber and is configured to use the rotating shaft as an axis. The pump substrate has a magnetism generating source. The rotating shaft protrudes into the pump chamber from the pump substrate, and is pivotally supported on the pump substrate. A magnetic fluid is disposed on at least one of spaces formed among the pump substrate, the rotating shaft, and the impeller.
