    • PROBLEM TO BE SOLVED: To provide a centrifugal pump device of which the length in the axial direction is reduced. SOLUTION: This centrifugal pump device has a motor unit and a pump unit. The motor unit has two slender stator units, and a rotor rotatable between the stator units on a motor housing unit. Each of the stator units is separated from a rotating shaft of the rotor and extends in the direction orthogonal to the rotating shaft. The pump unit has a pump chamber, a plurality of blades arranged in the pump chamber and fixed to the rotor, a pump housing unit fixed to the motor housing unit without gap, a liquid passage communicating with the pump chamber, an intake passage communicating with the liquid passage, and a discharge passage communicating with the pump chamber and extending at least partially within a region between the stators.
