Abstract
A sliding member according to the present invention is used in presence of lubricant oil, and includes a sliding surface made of a base material, and a recessed portion provided in the sliding surface, wherein the sliding surface satisfies a condition expressed by following Equation. 2 ≤ α / Ra ≤ 100 In Equation, α represents a ratio of a total volume of the recessed portion on the sliding surface to an area of a portion of the sliding surface in which the recessed portion is not formed, and Ra represents a center line average roughness of the sliding surface in the portion in which the recessed portion is not formed.
