Abstract

An iron-based sintered sliding member is provided in which solid lubricating agent is dispersed uniformly inside of powder particles in addition to inside of pores and particle interfaces of the powder, the agent is strongly fixed, and sliding properties and mechanical strength are superior. The iron-based sintered sliding member contains S: 0.2 to 3.24 mass %, Cu: 3 to 10 mass %, remainder: Fe and inevitable impurities, as an overall composition; the metallic structure includes a base in which sulfide particles are dispersed, and pores; the base is a ferrite phase or a ferrite phase in which copper phase is dispersed; and the sulfide particles are dispersed at a ratio of 0.8 to 15.0 vol % versus the base.
