A pipe joint includes a sleeve that is non-movably integrated with a nut prior to the nut being threadedly coupled to a joint body. The sleeve is separated from the nut by threadedly coupling the nut to the joint body prior to contact between the sleeve and a guide surface of the joint body so as to stabilize the separation timing of the sleeve from the nut and ensure the sealing property at portions where the sleeve bites. When the nut is further threaded to the joint body, a distal end portion of the sleeve is pressed by a guide surface formed on the joint body and deformed. As a guided surface is guided by the guide surface, the distal end portion bites into an outer peripheral surface of the pipe.
