A sliding variable resistance type main detector body 26 for detecting the surface level is provided, and a variable resistance type sub detector body 29 that can be switched by a switch is provided in the non-installation chamber 21b. A first resistor 34 is connected to the sub-detector main body 29 and increases the resistance value of the main detector main body to output a value corresponding to the zero position of the liquid level when the main detector reaches the zero position. Second resistors 31a, 31b, 3 forming a detection circuit
1c, 32 and third resistors 33a, 33b for correcting the resistance value of the main detector body are integrated on a single ceramic substrate 30. and sub-detector body 29
A liquid level detector characterized by electrically connecting in parallel.
