A sliding component is characterized in that dimples are provided on one sealing face of a pair of sliding parts that mutually slide relative to each other, where the cavitation formation area on the upstream side of each dimple is positioned closer to the low-pressure fluid side and the positive-pressure generation area on the downstream side is positioned closer to the high-pressure fluid side, and the fluid that has been suctioned in the cavitation formation area of each of the above dimples travels in the dimple and is returned to the high-pressure fluid side from the positive-pressure generation area.
