PROBLEM TO BE SOLVED: To provide a technique for having a simple constitution of a supply path for supplying liquid to a storage space.SOLUTION: A sensor device includes: a wall 66 that defines a storage space 120 for storing fuel; an electrode pair 100 that detects properties of the fuel inside the storage space 120; and a set plate 14 for closing an opening of a fuel tank. The set plate 14 protrudes inside the fuel tank 10 and has a support member 16 for supporting an electrode 104. The wall 66 has a communication port 67 that communicates the inside and outside of the storage space 120. The support member 16 has a through hole 16a that penetrates through the support member 16. One end of the through hole 16a is in contact with an end of the communication port 67 located outside the storage space 120. |
