A resin jointincludes an outer cylindermolded by a resin material capable of transmitting laser light and an inner cylinderdisposed facing the inner peripheral surface of the outer cylinder. An annular protrusionthat protrudes in the radial direction and extends in the circumferential direction is formed on the inner peripheral surface of the outer cylinderor the outer peripheral surface of the inner cylinder. The axial end of the resin tubeis inserted into an annular spaceand is deformed in the radial direction following the annular protrusion, and a region deformed in the radial direction has a surface that is in contact with the inner peripheral surface of the outer cylinder. The inner peripheral surface of the outer cylinderand the outer peripheral surface of the resin tubeare laser-welded.
