PROBLEM TO BE SOLVED: To obtain an inexpensive liquid level sensor having simple structure in which the residual quantity of fuel can be determined surely at a position different from a fuel tank. SOLUTION: A plurality of sensors 401, 402, 403, 404, 405 are arranged vertically at a predetermined interval while inserting the detecting parts thereof into a liquid level measuring part 3 made of a pipe material extending vertically. The liquid level measuring part 3 has upper and lower end parts 32, 33 communicating, respectively, with the upper and lower parts of a liquid storing section 2 and constructed to introduce the liquid in the liquid storing section. Each sensor outputs a liquid level detection signal when the liquid is present at each position and a liquid level indication meter indicates the liquid level depending on the liquid level detection signal. The plurality of sensors are fixed to the liquid storing section 2 while overlapping in plan view. |
