Claim Text:
1. A sliding component characterized in that: on one sealing face of a pair of sliding parts that slide relative to each other, multiple positive pressure-generating mechanisms that comprise extremely shallow parallel grooves running roughly in parallel with the sealing face and having a submicron-level depth are provided independently in a circumferential direction, and each extremely shallow parallel groove is a recess defined by two sides in the circumferential direction and a bottom wherein a side of the recess at a high-pressure fluid side is open thereto in a radial direction and communicates therewith, and a side of the recess at a low-pressure fluid side is open to and communicates with multiple extremely shallow thin grooves which are formed on the sealing face on the low-pressure fluid side of the extremely shallow parallel grooves, wherein each extremely shallow parallel groove communicates with a different set of multiple extremely shallow thin grooves, and the extremely shallow thin grooves are isolated from the low-pressure fluid side by a seal area.
