Abstract
The present invention is a flush toilet (1) including: a bowl portion (8) having a bowl-shaped waste receiving surface (16), a rim portion (18), and a well portion (20) formed at the bottom of the waste receiving surface; a discharge trap pipe (12) connected to the bottom portion of the well portion; a flush water guide portion (40b) disposed on the waste receiving surface at the rear of the well portion so that flush water is directed toward the side wall surface inside the well portion; and a liquid membrane spouting portion (24) disposed on the rim portion, wherein this liquid membrane spouting portion induces a vertical circulating flow in the well portion, produced when discharged flush water assumes a liquid membrane form and collides with a flush water guide portion, and the colliding flush water drops along the side wall surface of the well portion.
