PROBLEM TO BE SOLVED: To provide a method for manufacturing a pipe joint made of a resin of which the weld part, where a molten resin at the time of injection molding joins, is enhanced in strength. SOLUTION: In the method for manufacturing the pipe joint made of the resin, at the symmetric positions of the outer peripheral side surface of a joint main body, a gate for inserting the molten resin is provided to one side surface and a resin sump, where the molten resin is accumulated, is provided to the other side surface to perform injection molding. Further, a rib is provided to the other side surface of the joint main body, and the resin sump where the molten resin is accumulated is provided to the rib to perform injection molding.
