<P>PROBLEM TO BE SOLVED: To provide a resin pipe joint compatibly attaining pull-off resistance and good sealing performance, economically comprising two members, namely, a joint body and a union nut. Ž<P>SOLUTION: The resin pipe joint includes the fluororesin joint body 1 having an inner cylinder portion 4 having a tapered outer peripheral face 4b whose diameter is gradually larger toward the inner corner side, and a male screw portion 5, and the fluororesin union nut 2 having a female screw portion 8, a seal thrusting portion 10, and an anti-come-off thrusting portion 11. As the union nut 2 is threaded with the fastening operation in the state that a tube 3 is externally suitable for the inner cylinder portion 4 to form a diameter-enlarged portion 3A, a tapered externally fitted portion 9B is thrust toward an axial center P while being pushed in the radial direction by the anti-come-off thrusting portion 11 because the tapered outer peripheral face 4b has a gentle inclination angle β, and an small-diameter side end portion of the diameter-enlarged portion 3A is thrust toward the axial center P by the seal thrusting portion 10.
