Summary:PURPOSE: A sensor unit for a urea tank with a return pipe for defrosting frozen water is provided to rapidly defrost the frozen water without driving an engine by forming a heating cable and filler in a space between the inner and outer pipes of a dual pipe unit. CONSTITUTION: A sensor unit for a urea tank with a return pipe for defrosting frozen water comprises a head, a lead pipe, a heating pipe, a urea suction pipe, a urea return pipe(150), and a float. A plurality of nozzle holes(152) is formed on the outer surface of the return pipe, and discharges the urea to the urea tank. The nozzle holes are connected to an inner fluid path(151a). The float is coupled to the outer diameter of the lead pipe, and slides up and down according to the amount of the urea in the urea tank.
