A pair of sliding components are disposed at a relatively rotating position at the time of running a rotary machine and formed in an annular shape in which a sealed liquid is present on one side of an inner radial side and an outer radial side and a gas is present on the remaining side thereof. A sliding surface of a sliding component is provided with a dynamic pressure generation groove which communicates with the side of a gas in a radial direction and which is configured to generate a dynamic pressure between the sliding surfaces by the gas at the time of running the rotary machine. A sliding surface of a sliding component is provided with a groove which extends in a circumferential direction.
