PROBLEM TO BE SOLVED: To provide a water supply device capable of supplying flushing water at a sufficient instantaneous flow rate to a toilet bowl even if a tank smaller in volume than a low tank is used, the pipe diameter of water line piping is small, water line pressure is not sufficiently high, or the like, and to provide the toilet bowl equipped with the water supply device, and a toilet bowl flushing method. SOLUTION: A water valve 2, an air valve and an atmosphere open valve 13 are opened in the initial stage of flushing. Water is thereby supplied from a water tank 8 to the toilet bowl 20 at a flow rate W<SB>1</SB>. The air valve 9 is then closed. Water is thereby supplied from the water tank 8 to the toilet bowl 20 at the total water flow rate W<SB>2</SB>=W<SB>1</SB>+A<SB>1</SB>, wherein W<SB>1</SB>is the quantity of newly supplied water, and A<SB>1</SB>is the flow rate of air flowing in through the atmosphere open valve 13. A suction valve 16 is opened further later to suck the secondary side of a trap 24. A powerful siphon is thereby formed early in the trap 24. After starting the siphon, the atmosphere open valve 13 is opened, and the suction valve 16 is closed to allow water to flow at the toilet bowl supply water quantity W<SB>2</SB>and to hold the siphon.
