Provided is a sliding component that, while achieving both the opposing conditions of sealing and lubricating, by means of actively taking in, discharging, and recycling a fluid at the sliding surface, prevents the occurrence of deposits at the sliding surface and is able to maintain the sealing functionality of the sliding surface over the long term. The present invention is characterized in that a fluid recycling groove (10) that is configured from an entrance section (10a), which enters from a high-pressure-fluid side, an exit section (10b), which leads to the high-pressure-fluid side, and an interconnection section (10c), that interconnects the entrance section and exit section, is provided to one of the sliding surfaces at which a pair of sliding components slide relative to each other, the fluid recycling groove (10) is isolated from a low-pressure-fluid side by a land section, a positive pressure generation mechanism (11) is provided to a section encircled by the fluid recycling groove (10) and the high-pressure-fluid side, the positive pressure generation mechanism (11) interconnects with the entrance section (10a), and the exit section and high-pressure-fluid side are isolated by a land section (R). |
