Claim 0:
1. A sliding component formed in an annular shape and disposed at a relatively rotating position of a rotary machine,
the sliding component comprising: a dynamic pressure generation groove provided in a sliding surface of the sliding component, the dynamic pressure generation groove having a first end forming a closed end and a second end forming an inlet communicating with any one side of a sealed fluid side and a leakage side in a radial direction; and
a deep groove provided in the sliding surface and deeper than the dynamic pressure generation groove, an inlet of the deep groove communicating with the inlet of the dynamic pressure generation groove on a side of a side wall of the dynamic pressure generation groove, the side wall being circumferentially opposite to a dynamic pressure generation wall constituting another side wall of the dynamic pressure generation groove, wherein
the deep groove is shorter in radial length than the side wall of the dynamic pressure generation groove circumferentially opposite to the dynamic pressure generation wall of the dynamic pressure generation groove, and wherein the dynamic pressure generation groove is circumferentially wider than the deep groove.
