PROBLEM TO BE SOLVED: To improve water supply performance of a water supply device for supplying water from a water tank of a coffee extractor, a humidifier, and the like to a water receiving part via a stopcock valve. SOLUTION: The water supply device includes: the water tank; a cap provided at an opening on one end side of the water tank; the stopcock valve for closing a water outflow port provided in the cap; the water receiving part for storing a predetermined amount of water flowed out via the water outflow port, and then supplying the water to a required portion; and a stopcock valve opening member provided in the position corresponding to the water outflow port of the water receiving part and inserted into the water outflow port to open the stopcock valve when the water tank is installed in the water receiving part. The stopcock valve has a flap structure enabling vertical rotation around one end side to open/close the inlet side of the water outflow port of the cap. This enables secure water supply.
