PROBLEM TO BE SOLVED: To provide a liquid level sensor of a simple and compact structure capable of continuously and highly accurately detecting the location of the liquid level and superior in resistance to corrosion. SOLUTION: Electrodes (1c) and (1d) of the liquid level sensor (S) are formed by coating the external circumference of a resistance wire (1a) with a conductive member (1b) to acquire two resistance wires (1), arranging the two resistance wires (1) at an interval in their longitudinal direction, and coating tip parts of the two resistance wires (1) with a conductive member (1e).
