In an exemplary embodiment, a sliding component includes a pair of sliding parts 4 and 7 sliding relatively to each other and having sliding faces S formed radially for sealing a liquid or a misty fluid as a sealed fluid against leakage. One sliding part is a stationary-side seal ring 7, and the other sliding part is a rotating-side seal ring 4. At least one of the sliding faces S is provided with positive pressure generation mechanisms 11 having positive pressure generation grooves 12 configured to communicate with a circumferential edge of the sliding face S on the sealed-fluid side and not to communicate with a circumferential edge on the leakage side, and discharge grooves 10 disposed at an angle such that upstream ends are located on the leakage side and downstream ends are located on the sealed-fluid side.
