Abstract
A friction couple including: a first friction member that contains a metallic material and includes a first friction surface; and a second friction member that includes a second friction surface that contacts the first friction surface and that contains an oxidation film developer that accelerates formation of an oxidation film on at least one of the first friction surface and the second friction surface by oxidizing the metallic material when the first friction surface and the second friction surface contact each other.
