PROBLEM TO BE SOLVED: To provide a drainage connector capable of properly discharging waste water from a toilet bowl body. SOLUTION: The drainage connector 10 connects an outlet 3A of a toilet bowl drain channel 3 which communicates with a downstream side of a toilet bowl 2 provided in a toilet bowl body 1, and an inflow port 5A of a drain pipe 5 opened into a toilet room R in which the toilet bowl body 1 is installed. The drainage connector 10 includes: an upstream-side opening 11 which is connected to the outlet 3A; a descending pipe 12 which is elongated downward from the upstream-side opening, and forms a descending channel L1 comprising intermediate throttles 12B and 12C becoming smaller in longitudinal channel width than an upstream end 12A and becoming larger in horizontal channel width than the upstream end; and a downstream-side opening 13 which is formed at the downstream side of the descending pipe 12 and connected to the inflow port 5A.
