PROBLEM TO BE SOLVED: To provide a liquid level detector capable of strengthening the tolerance of a magnet.SOLUTION: A liquid level detector includes: a holder 20 rotating according to displacement of a float 50 in association with variation of a liquid level; a magnet 25 which is fixed to the holder 20 and which rotates together with the holder 20; and a magnetic detection element 14 for detecting a variation of magnetic force in association with rotational motion of the magnet 25. The magnet 25 is formed of a first magnet 25a and a second magnet 25b which covers the first magnet 25a and which hardly corrodes.SELECTED DRAWING: Figure 2 |
