PROBLEM TO BE SOLVED: To provide a flush toilet bowl which can downsize a pressure accumulation container for storing pressurized flush water therein. SOLUTION: The flush toilet bowl (1) is flushed with water directly supplied from a feed pipe of waterworks, and has a bowl section (2) provided with rim outlets at an upper portion thereof; a trap section (4) communicating between a bottom of the bowl section and a drain pipe; a jet nozzle (6) for ejecting flush water toward the trap section; the pressure accumulation container (12) for storing therein flush water supplied from the feed pipe of the waterworks in such a state that the flush water is pressurized to a pressure higher than that of tap water; a spout valve (20) arranged on a downstream side of the pressure accumulation container, and opened at the time of flushing the bowl section, to thereby eject the flush water from the jet nozzle; and pressurizing means (14, 16, 18) for increasing water pressure in the pressure accumulation container, for spouting from the jet nozzle in the following flushing, during current spouting operation from the rim outlets.
