Provided is a fluid pump including: a motor unit that comprises a stator, a rotor, and a rotational shaft on which the rotor is fixed, to thus generate a rotating torque; a pump unit that is placed separately from the motor unit on one side of the motor unit, and that comprises an impeller for pumping fluid: a first power transmission unit that is fixed to the rotor and is rotated with the rotor, and that comprises a first magnet; and a second power transmission unit that is fixed to the impeller and that comprises a second magnet that is disposed facing the first magnet and has opposite polarities to those of the first magnet. Accordingly, fluid can he fundamentally prevented from being introduced into the inside of the motor unit
