Abstract

A sliding bearing formed from a member containing resin, wherein the effect of thermal expansion of the resin is reduced. A bearing surface (10) that slidably holds the outer peripheral surface of a rotating body is formed on the inner peripheral surface (11) of the sliding bearing (1), which is cylindrical, and the sliding bearing (1) is a cylindrical multi-layer sliding member which is manufactured by roll-molding a base material that has been impregnated with a base resin. A plurality of through-holes (13) that pass between the inner peripheral surface (11) and the outer peripheral surface (12) are formed at suitable intervals in the bearing surface (10) and within a range that enables the sliding bearing (1) to maintain a required load-bearing strength. A solid lubricant (14) that has higher thermal conductivity than air and a lower thermal expansion coefficient than the base resin is embedded in the through-holes (13) in accordance with a required sliding performance and use conditions (such as the continuous use time in the atmosphere). A substance comprising graphite alone, a substance made of a resin that contains graphite, or the like is used as this type of solid lubricant (14).
