Abstract: A centrifugal blood pump for circulating blood is provided, wherein an impeller makes no contact at all with a housing and a rotating shaft and moves in a rotating manner with the impeller in a stably levitating state. Also provided is a blood pump in which the impeller rotates at high speed even when the blood pump is reduced in scale. The blood pump contains a magnet of enhanced magnetic force at the inside of a housing and at an outer peripheral surface of an impeller and providing a fixed-interval spacing on the periphery of a bearing section makes it possible to ensure a state where no contact at all is made between the housing, a shaft, and the impeller, and makes it possible to cause the impeller to rotate stably over a long period of time.
