<p>PROBLEM TO BE SOLVED: To provide a technique capable of smoothly discharging bubbles which enter a space between electrodes outside of the space between the electrodes.SOLUTION: A liquid quality sensor 60 includes: an electrode 106 including an outer peripheral surface 106a; an electrode 104 including a facing surface 104b; and a storage space 120 defined with the outer peripheral surface 106a and the facing surface 104b. The storage space 120 stores fuel. In the storage space 120, an outlet 62c for discharging the fuel in the storage space 120 outside of the storage space 120 is arranged above the outer peripheral surface 106a and the facing surface 104b.</p> |
