PROBLEM TO BE SOLVED: To provide a faucet device capable of starting water discharge at optimum timing by surely detecting the operation of a detected body for water discharge without erroneous detection caused by water sticking to the inside wall surface of a water receiving part which flows along the inside wall surface of the water receiving part. SOLUTION: The faucet device includes: a water discharge part for discharging a discharge flow from a water discharge port; a valve for switching the discharge and cut-off of water from the water discharge part; the water receiving part for receiving the discharge flow discharged from the water discharge port; a sensor acquiring information on the detected body by the reflected wave of a radiated radio wave; and a control part for controlling the opening/closing of the valve based on detection signals from the sensor. The sensor is disposed near the wall surface of the water receiving part. The control part places the valve in opening operation when it is detected that a voltage value of the detection signal is not higher than a second threshold lower than a reference value which is a substantially the central value of amplitude of the detection signal within a first predetermined time after the voltage value becomes not lower than a first threshold higher than the reference value.
