摘要： A flush toilet includes a shelf formed on the top edge of a bowl-shaped waste receiving surface, and a rim forming an inner wall surface rising from the outer edge of the shelf. The bowl includes a front side region and a rear side region, respectively, formed on the front side and the rear side of a center axis extending horizontally in the left-right direction so as to divide the bowl equally in the front-rear direction. The inner wall surface includes an overhang portion protruding toward inside of the bowl obliquely from the bottom end of the overhang portion. The ratio between the overhang amount and the width of the shelf is set smaller than 1.0.
