A water level sensor is provided to determine the arrangement in a water tank easily and to allow the application to a built-in structure such as bidet. A water level sensor comprises a stem(100) having an insertion part(105) which is tightly fitted to the wall of a water tank and an internal space, a magnetic sensor which is installed inside the stem and senses the change of magnetic force, and a floater(120) which is attached to the stem and rotates to be close to or away from the leading end of the stem. The floater has a magnet which causes the change of magnetic force with respect to the magnetic sensor. |
