A sensor device (1) is provided with a fuel flow path through which fuel discharged from a fuel pump (4) in a fuel tank (2) flows, and a detection electrode (61) that makes contact with the fuel flowing through the fuel flow path to detect the alcohol concentration (a first property of the fuel) contained in the fuel. The fuel flow path is provided with a throttle (25) (a first resistance portion) downstream of the detection electrode (61) as resistance to the flow of fuel. |
