Abstract
A sliding member (12) is disclosed that has superior slidability and durability at a low cost. A top sliding surface (12a) of the sliding member (12) is formed by a nitriding process that creates a compound layer (14) and a diffusion layer (15) on a base metal (16) of the sliding member (12). The buff polishing process is thinly performed on an outermost layer portion (14a) of the compound layer (14), such that a portion of the compound layer (14b and/or 14c) remains.
