PROBLEM TO BE SOLVED: To provide a siphon type toilet bowl that reliably reduces noises at an end of siphoning with a small quantity of flush water. SOLUTION: The siphon type toilet bowl has a bowl part with an outlet, a trap part interconnecting a riser line part forming a line rising from an inlet in communication with the outlet and a downcomer line part forming a line bent down to the downstream side of a top portion of the riser line part, and a jet hole for jetting aerated water as flush water mixed with bubbles into the bowl part. The jet hole is defined to jet aerated water toward an upper half of the inlet that is the upper portion of substantial vertical bisections of a longitudinal section of the inlet.
