PROBLEM TO BE SOLVED: To provide an electrode for liquid level detectors which is simple in structure manufacturable with free dimensions fit to the measuring range and the shape of a tank and easy to mount. SOLUTION: To change the capacitance with the change of a liquid surface level, the sensor is composed of a dielectric-covered electrode A composed of a rod-like conductor covered with a dielectric, a conductor electrode B for electric connection with a liquid under test, and an electrode fixing material C formed as a mounting structure on a tank top for electric insulation between the electrodes A, B and for mechanical holding of the electrodes. The electrodes A, B are disposed with a space for allowing the liquid under test to enter around the electrode A.
