PROBLEM TO BE SOLVED: To disclose a technology capable of suppressing a contact of a foreign matter with an electrode pair.SOLUTION: A sensor device 2 includes: a jet pump 44 for making a reserve cup 20 discharge fuel; and an electrode pair placed in a direction in which fuel is discharged from a discharge port of the jet pump 44. The electrode pair is placed on a second plate 66 of a substrate 62. In the electrode pair an electrostatic capacitance varies depending on liquid quality of the fuel. |
