Abstract
A flush toilet includes a bowl part that includes a waste-receiving surface with a bowl shape that receives waste and a rim part that extends upward on an upper edge part of the waste-receiving surface, a first water-spouting port that spouts a washing water toward the rim part to form a first flow of a washing water that swirls on the waste-receiving surface, a second water-spouting port that spouts a washing water toward the rim part to form a second flow of a washing water that joins the first flow, and a connection part that includes a concave surface that connects the waste-receiving surface and the rim part and is curved to have a curvature that decreases from an upstream side to a downstream side of the first flow just before the first water-spouting port or the second water-spouting port in a flow direction of the first flow.
