A centrifugal pump (10) includes a housing (26), an impeller (28) that is rotatably disposed inside the housing (26), a shaft (62) that is provided at a center in a radial direction of the impeller (28), and bearings (70) that respectively and pivotally support shaft ends (66) provided on both sides of the shaft (62) in an axial direction. At least one of the shaft ends (66) has surface roughness Ra equal to or less than 0.21 µm or surface roughness Ry equal to or less than 1.49 µm.
