PROBLEM TO BE SOLVED: To provide a measurement device which integrates a component penetrating through a lid member and thereby reduces the number of seal portions and simplifies the structure.SOLUTION: A measurement device 1 measures characteristics of a fuel in a fuel tank and includes: a lid member 4 which closes an opening part 3 formed in the fuel tank 2; a plug member 20 which closes a through hole 5 formed at the lid member; and a sensor 28 which measures the characteristics of the fuel in the fuel tank. The plug member 20 includes: an electric connection part 22 which penetrates from an upper surface of the plug member 20 to a lower surface and electrically connects the interior of the fuel tank with the exterior; and a fuel passage 21 having an opening part which opens to the interior of the fuel tank. The sensor 28 is disposed in the fuel passage 21 of the plug member 20. |
