A fluid is actively taken into sealing faces and discharged from the sealing faces so as to prevent concentration of sediment causative substances on the sealing faces and hence prevent generation of sediment while preventing leakage of the fluid taken into the sealing faces to a low pressure fluid side. Thereby, a sealing function of the sealing faces is maintained for a long time. A fluid circulation groove 10 including an inlet side section 11 where the fluid comes in from a high pressure fluid side and an outlet side section 12 where the fluid goes out to the high pressure fluid side is provided in one of sealing faces S of a pair of sliding parts that slide on each other. The fluid circulation groove 10 is isolated from the low pressure fluid side by a land section R. Groove width of the outlet side section 12 of the fluid circulation groove 10 is gradually expended toward an outlet end. |
