A sliding member according to an aspect of the present disclosure includes: a sliding member body containing a metal as a main component; and an outer layer laminated directly on a surface of the sliding member body and containing a crosslinked fluorine resin as a main component, and an arithmetic average roughness Ra1 of a surface having a waveform obtained by extracting a frequency component of a region having waviness having a frequency of not lower than 0.1 μm and not higher than 100.0 μm on a surface of the outer layer through fast Fourier transform processing, and performing inverse Fourier transform processing on data of a frequency component of a region having waviness having a frequency of not lower than 0.1 μm and not higher than 10.0 μm out of the extracted frequency component, is not greater than 0.035 μm.
