PROBLEM TO BE SOLVED: To provide a synthetic resin-made curved pipe joint capable of preventing destruction due to concentrated stress and fatigue, providing satisfactory efficiency in increase of wall thickness, and suppressing increase of weight of the whole joint by increasing wall thickness for stress effectively. SOLUTION: A central axial line of outside diameter of a curved part of the curved pipe joint is deviated close to an inner side of the curved part of a curved pipe for a central axial line of inside diameter, and wall thickness is gradually changed from a thick wall part on an inner side toward a thin wall part on an outer side.
