Abstract
Provided is sliding components capable of stably obtaining a low-friction effect even in a non-lubricated environment. Sliding components and have sliding surfaces and performing relative sliding. A carbon film in which a polymer structure is dispersed is formed on the sliding surface of the sliding component. The proportion of the polymer structure dispersed in the carbon film is such that an extinction coefficient of 0.2 or less and a refractive index of 1.5 to 2.0 are satisfied in a wavelength range of 550 nm of spectroscopic ellipsometry.
