IRON BASE SINTERED SLIDING MEMBER AND METHOD FOR PRODUCING SAME

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: 3.24 to 8.10 mass %, remainder: Fe and inevitable impurities, as an overall composition; the metallic structure includes a ferrite base in which sulfide particles are dispersed, and pores; and the sulfide particles are dispersed at a ratio of 15 to 30 vol % versus the base.
