Abstract
A sliding component includes a plurality of dimples 10 disposed on at least one of sliding surfaces of a pair of sliding parts relatively sliding on each other, the plurality of dimples 10 is provided mutually independently of the other dimples, and the plurality of dimples 10 has an area ratio set lower on the low-pressure fluid side of the sliding surface than on the high-pressure fluid side. On the sliding surface, a liquid film on the high-pressure fluid side is thickened by dynamic pressure effect to improve fluid lubricity, and a liquid film on the low-pressure fluid side is thinned to prevent leakage.
