Provided is a sealing ring that suppresses leakage of a fluid to be sealed and that is capable of stably reducing rotational torque. A sliding surface side is provided with a groove portion (120) that comprises a first groove (121) extending in the circumferential direction and a second groove (122) that extends from a central position of the circumferential direction in the first groove (121) to an inner circumferential surface and that guides the fluid to be sealed into the first groove (121), characterized in that the first groove (121) comprises a groove for generating dynamic pressure (121a) formed such that the groove bottom is shallower in the end portions of the circumferential direction when compared to the center of the circumferential direction and a groove for capturing foreign objects (121b) capable of capturing foreign objects, the groove bottom of which is deeper than the groove bottom of the groove for generating dynamic pressure (121a), and in that the first groove (121) is provided in a position fitting into a sliding region that slides with respect to a side wall surface. |
