[Problem] Provided is a centrifugal pump in which a thrombus can be effectively prevented or restrained from being formed inside a blood inlet port.[Solution] A centrifugal pump 1 includes a housing 2 that is provided with a housing main body 20, a blood inlet port 25, and a blood outlet port 26； a rotary body 3 that is rotatably accommodated inside the housing main body 20； and a support mechanism 4 that supports the rotary body 3. The support mechanism 4 is provided with a rod-like shaft member 5, and a first bearing 6 and a second bearing 7 which respectively and rotatably support end portions of the shaft member 5. In addition, a lower surface 62 of the first bearing 6 is positioned at the same distance as an inner peripheral surface 255 of the blood inlet port 25 from a central axis O of the blood inlet port 25 or is positioned so as to be closer to the central axis O side of the blood inlet port 25 than the inner peripheral surface 255 of the blood inlet port 25.
