Abstract
A sliding component includes a stationary-side seal ring and a rotating-side seal ring. The stationary-side seal ring and the rotating-side seal ring have their respective sliding faces opposite to each other. The sliding faces are relatively rotated, thereby sealing a high-pressure fluid present on one radial side of the sliding faces relatively rotationally sliding. At least one of the stationary-side seal ring and the rotating-side seal ring includes a substrate, an adhesion layer on the sliding face side of the substrate, and a glassy carbon sheet member stuck on the substrate via the adhesion layer.
