Abstract: A flush toilet bowl comprises a bowl part (1) and a discharge trap (2) formed continuously at the bottom of the bowl part, and the discharge trap (2) further comprises a rising channel (22) extending in the obliquely upward direction from the bottom of the bowl part, a first weir (27) formed at the upper end of the rising channel, a descending channel (23) extending downwardly from the first weir, and a cross-laid channel (24) extending substantially in the horizontal direction from the lower end of the descending channel and having a discharge opening (25) at the end. The cross-laid channel (24) is provided with an upwardly bent second weir (28) between the lower end of the descending channel and the discharge opening, and a gathered water part (29) is formed between the second weir (28) and the lower end of the descending channel and, simultaneously, the descending channel is formed in the vicinity of the lower end thereof with a horizontal part (26) extending horizontally toward the cross-laid channel (24).
