PROBLEM TO BE SOLVED: To provide a resin pipe joint which makes it possible to avoid the addition of manufacturing facilities and the complication of a manufacturing method by allowing the generation of a weldline while substantially preventing the problems of cracking or the like due to the weldline from occurring by changing the position or direction of the weldline, and a method for manufacturing the resin pipe joint. SOLUTION: The resin pipe joint is manufactured by injection molding and constructed so that the weldline L which is generated when a molten resin is injected in the cavity of a mold to be injection-molded, appears at a part other than a load concentrating part of the resin pipe joint during use.
