Zusammenfassung:	A seal ring capable of stably reducing a rotational torque while preventing the leakage of sealed fluid. The seal ring includes: an abutment joint part (110) provided at one portion in a circumferential direction thereof; a plurality of dynamic pressure generation grooves (120) provided at intervals in the circumferential direction on a side of a sliding surface thereof sliding on a lateral wall surface of an annular groove; and foreign matter discharging grooves (130) that are provided between a region in which the plurality of dynamic pressure generation grooves (120) is arranged and the abutment joint part (110) in the circumferential direction on the side of the sliding surface sliding on the lateral wall surface, and that are capable of catching foreign matter intruding from the abutment joint part (110) and discharging the caught foreign matter to an outside of a sliding part between the seal ring and the lateral wall surface.
