Abstract: The present invention is a discharge socket connecting a toilet main body and a discharge pipe. The discharge socket has a vertical conduit portion; and a bent conduit portion including an inflow port connected to the vertical conduit portion; an outflow port, connected to an inlet port of the discharge pipe; and a flow path, the flow path having a bent portion. A projecting portion is disposed on the bent portion, the projecting portion forming a projecting space which projects outward from the flow path. The projecting portion is formed so that the flow direction of discharge water flowing from the bent conduit portion into the inlet portion of the discharge pipe is changed to the center direction of the discharge pipe by the discharge water returning to the projecting space after flowing from the flow path into the projecting space.
