PROBLEM TO BE SOLVED: To provide a flush toilet bowl which can generate siphon action at an early stage while preventing clogging of dirt. SOLUTION: The flush toilet bowl has a trap drain 6 provided with an upright upper pipe line 12 and an upright lower pipe line 14, and has bending pipe lines 16, 26, 30, 40 and lateral drain pipe lines 18, 32 or longitudinal drain pipe lines 28, 42. The bending pipe lines 16, 26, 30, 40 are connected to the lower end of the upright upper pipe line 12 of the trap drain 6 and the lateral drain pipe lines 18, 32 or the longitudinal drain pipe lines 28, 42 are connected to the down-stream end of the bending pipe lines. The flush toilet bowl is formed in a flat surface shape 20 so that the washing water falling from the upright lower pipe line on the inner undersurface of the bending pipe lines jumps toward the position close to the upper end of the entrance of the lateral drain pipe lines or the longitudinal drain pipe lines.
