Abstract
In an embodiment, in a slide component, a negative pressure generation mechanismthat generates negative pressure by relative rotational sliding of a stationary-side seal ringand a rotating-side seal ringis provided on a sealing face of one of the stationary-side seal ringand the rotating-side seal ring, and at least the surface of the negative pressure generation mechanismis covered by an adhesion-resistant material film. With the configuration, deposition of precipitates on a negative pressure portion of a sealing face can be inhibited.
