Abstract: A flush toilet includes a first rim spout port provided in a rim on one side in a left-right direction of a bowl and a second rim spout port provided in the rim on the other side in the left-right direction of the bowl. The first rim spout port is disposed further in the front than the front end of a well portion. The second rim spout port causes the second rim spout to traverse a swirling direction of a swirling flow of the first rim spout and guide the flush water interfering with the swirling flow of the first rim spout to a rear region of the bowl further on the rear side than the well portion.

Abstract: A water passage in a front region of a bowl of a toilet includes an upstream side water passage and a downstream side water passage formed on the upstream side and on the downstream side, respectively, of a front end of the bowl surface. The curvature radius of the downstream side water passage in a plan view is set to be smaller than the curvature radius of the upstream side water passage in a plan view. The water passage in the front region of the bowl has a flow path vertical cross-section that is taken in the vertical direction and is formed between a shelf surface and an overhanging part. The cross-sectional area of the flow path vertical cross-section taken in the vertical direction is set to be the smallest in a front end of the water passage.
