The flush water flows as at least two water flows that comprise a main flow (F1) that flows along the upright surface part (11) around a circumferential edge of the toilet bowl (10) and a sub-flow (F2) that branches from the main flow (F1) and flows down the bowl surface part (12). The sub-flow (F2) merges with the main flow (F1) at a downstream-side merge part (J).
