SOLUTION: An automatic faucet comprises a sensor including a light emitting part 62 and a light receiving part 64 in a water ejection pipe 12 and automatically discharges water from a discharge port 58 based on a detection of an object with the sensor. A light emitting window 100 and a light receiving window 102 are independently arranged apart from each other in the front face of a installation part 114 of the light emitting part 62 and the light receiving part 64, and the portion between a light emitting window 100 and a light receiving window 102 of the installation part 114 is formed as a concavity 118 which is concaved inward.
