<p>This liquid level detection apparatus is provided with: a fixed body (20), which has a fixed body main section (22) that is fixed to a container (90) having a liquid stored therein, and a shaft section (23, 223, 323) that cylindrically protrudes from the fixed body main section (22); a float (30), which is formed to float in a liquid, and is provided with an insertion hole (31) for having the shaft section (23, 223, 323) inserted therein, said float being assembled to the fixed body (20) such that the float can move in the vertical direction (VD) by having the shaft section (23, 223, 323) inserted in the insertion hole (31); a magnet section (50), which is held by means of the float (30), and generates a magnetic field; and a switch mechanism (40), which is housed in the shaft section (23, 223, 323), and has the state thereof switched from an off-state to the on-state due to proximity of the magnet section (50). In a cross-section of the shaft section (23, 223, 323), a height (h) in the vertical direction (VD) is smaller than a width (w) in the horizontal direction (WD).</p> |
