    • An outer electrode projects from an opening, which is formed in an upper inner wall of a fuel passage, into the fuel passage. The fuel passage is adapted to conduct fuel generally in a horizontal direction. The outer electrode includes a fuel chamber in an inside of the outer electrode. An inner electrode is placed in the fuel chamber. A sensing circuit senses an alcohol concentration of the fuel based on an electrical property between the outer electrode and the inner electrode and a fuel temperature, which is sensed with a thermistor. The outer electrode includes a blocking portion and communication holes. The blocking portion limits intrusion of air bubbles, which flow along the upper inner wall of the fuel passage, into the communication holes.
