PROBLEM TO BE SOLVED: To provide a sensor device in which an electrode for specifying the liquid level of liquid, the concentration of a specific substance in the liquid, and the temperature of the liquid is properly disposed on a substrate.SOLUTION: A sensor device 10 includes: a substrate 11; a liquid level electrode 12 disposed on the substrate 11, and to which a signal is supplied from the outside for detecting a liquid level; a liquid quality electrode 14 disposed on the substrate, and to which a signal is supplied from the outside for detecting a concentration; a thermistor electrode 18 disposed on the substrate, and to which a signal is supplied from the outside for detecting a temperature; and a reference electrode 16 disposed on the substrate. The reference electrode 16 is disposed between the liquid level electrode 12 and the thermistor electrode 18, and between the liquid quality electrode 14 and the thermistor electrode 18. |
