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 is opened in the initial stage of flushing, and an air valve 9 is left open. Water is thereby supplied to the toilet bowl 20 from the tank 8 at a flow rate W<SB>1</SB>. In the latter stage of flushing, the air valve 9 is closed. Air flowing into the tank 8 together with water from an ejector 4 through piping 7 is thereby retained in the tank 8, and water in the tank 8 is supplied from the 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 inflow air. A powerful siphon is thereby formed early in a trap 24. COPYRIGHT: (C)2008,JPO&INPIT
