In this sliding component, a fluid-lubricated sliding surface has low friction during steady-state operation, and leaks of the sealed fluid and ingress of dust into the sliding surface are prevented. This sliding component is characterized in that: on the sliding surface of at least one of a pair of sliding components, hydrodynamic grooves 10 are provided such that the sealed fluid side and the leaky side are separated in a non-communicating manner by means of land portions on both sliding surfaces; between the leaky side and the leaky-side end portion 10a of the hydrodynamic grooves 10, fluid introduction grooves 11 are provided which allow communication between the hydrodynamic grooves 10 and the leaky side; and the cross-sectional area of the fluid introduction grooves 11 is less than the cross-sectional area of the hydrodynamic grooves 10. |
