Abstract: A problem is to provide a sliding member capable of easily improving friction characteristics, and a production method therefor. A solution is a sliding member 10, wherein a sliding portion 11 is formed of a metallic material, and the sliding member 10 has, on a surface of the sliding portion 11, a Cr-containing modified layer 12 formed by blasting a shot media containing Cr as a composition. The sliding member 10 slides under an environment of a lubricant containing Mo as an additive, in which active Cr exposed on the surface by sliding accelerates decomposition reaction of the additive contained in the lubricant to form a molybdenum disulfide-containing film having low friction on the surface of the sliding portion 11.
