Abstract: A flush toilet of present invention includes a bowl that includes a bowl-shaped waste receiving surface, a rim formed above the waste receiving surface, and a pooled water portion formed below the waste receiving surface, a discharge passage that has an inlet connected to the pooled water portion and discharges waste, and a spout portion that spouts flush water onto the bowl and forms a swirling flow on the waste receiving surface. The waste receiving surface of the bowl has a sectorial recess that is formed between a front end portion of the waste receiving surface and a front end portion of the pooled water portion so as to spread from the pooled water portion toward the front end portion of the waste receiving surface.
