Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid supply device capable of compatibly achieving the both of reducing the weight of the device and controlling the electromagnetic noise to be transmitted from an electric motor to the periphery thereof.SOLUTION: An HV cooling system 1 has a pump 2 with an electric motor, which includes a pump 21 and the electric motor 22, and supplies conductive cooling water to a predetermined supply-target member by the pump 2 with the electric motor via a hose 3. In the HV cooling system 1, there are provided: a casing 20, which accommodates the pump 21 and the electric motor 22 and is formed with a non-conductive material; and metallic pipe members 41, 42 for making conductive liquid pass through the midstream portion or end of the hose 3; wherein the pipe members 41, 42 are grounded. Thus, the electromagnetic noise to be transmitted to the periphery can be controlled irrespective of the conductivity of cooling water and the path length of the hose 3 forming an antenna for transmission.
