The present invention relates to a fluid level sensor-attached motor pump for a washer fluid, in which a fluid level sensor for detecting the remaining amount of a washer fluid stored in a washer fluid reservoir and outputting a detection signal is integrally mounted to a motor pump for a washer fluid so that an operator can check the remaining amount of the washer fluid through a dashboard of a vehicle and thus can replenish an insufficient washer fluid, in which the fluid level sensor is integrally mounted to the motor pump for a washer fluid to solve a problem in that the motor pump and the fluid level sensor are separately wiring-connected to the washer fluid reservoir to thereby deteriorate workability of wiring so that workability of wiring can be increased and the wiring can be simplified to reduce a defective proportion, in which the motor pump for a washer fluid and the fluid level sensor are integrally manufactured so that the manufacturing cost can be reduced, and in which the fluid level sensor for detecting the remaining amount of a washer fluid and outputting a detection signal is manufactured by selecting any one of a combination of a magnet and a Hall sensor, a combination of a magnet and a reed switch, and a combination of a Hall sensor and a buoyancy device mounted with a magnet so that the improvement in performance can be achieved through the use of a magnetic Hall sensor having reliability.
