An automatic water faucet device 1 includes: an electrolysis tank 37 that electrolyzes water to generate electrolyzed water; a second water discharge part 13 for discharging the electrolyzed water, a second flow path 18 that extends from the electrolysis tank 37 to the second water discharge part 13; a second solenoid valve 28 that switches between supply and blocking of normal water with respect to the electrolysis tank 37, and a controller 40 that controls the electrolysis tank 37 and the second solenoid valve 28. The controller 40 energizes the electrolysis tank 37 to discharge the electrolyzed water and thereafter stops the energization of the electrolysis tank 37 and maintains an open state of the second solenoid valve 28, to stop the supply of the electrolyzed water to the second flow path 18 and to supply normal water to the second flow path 18.
