The objective of the present invention is to enable an improvement in sliding characteristics over a wide range of the characteristic number of bearings in a sliding surface, and to generate a prescribed dynamic pressure by means of dimples with good machining precision. Therefore, this sliding component, which has multiple dimples (10) arranged on at least one of the sliding surfaces (S) on a pair of sliding components (3, 5) sliding relative to one another, is characterized in that the multiple dimples (10) are provided independently of other dimples and are arranged in a random distribution, with each dimple (10) being formed by means of an ultrashort pulsed laser beam and being a shallow groove with a depth in a range of 0.05-5 μm, and the roughness Ra of the bottom surface of the dimple being no greater than 1/10 of the machining depth. |
