ベルセンサ。[Claims for Utility Model Registration] An electrode member disposed through a liquid whose conductivity changes depending on temperature, and a detection circuit that converts an input signal obtained by applying an external current to the electrode member into a detected value signal. In the liquid level sensor, a temperature sensor whose resistance value changes depending on the temperature is provided in the liquid, and the temperature sensor is connected in series with the electrode member so that a temperature-corrected detection value signal is obtained from the detection circuit. A liquid level sensor characterized by connecting a temperature sensor.
