PROBLEM TO BE SOLVED: To provide a seal ring capable of reducing a torque, and capable of improving productivity. SOLUTION: This seal ring 100 is formed by arranging a recessed part 120 recessed further than a surface sliding on the side wall surface of an annular groove, along the inner peripheral edge on the side surface 103 of a seal ring body so that a thickness in the axial direction of the seal ring body becomes thinner on the inner peripheral side than the outer peripheral side, and is characterized in that the external shape, when viewing the recessed part 120 in the axial direction of the seal ring body is circular, and the center of this circle becomes a position dislocated to the opposite side of a cutting part 110 to the axis of the seal ring body.
