PURPOSE: To easily produce a sliding member excellent in machinability and aluminum adhesion resistance by compacting/sintering the mixed powder consisting of iron base metal powder and solid lubricant having covered layer and impregnating Al base metal in pores of sintered body.

CONSTITUTION: A mixed powder consisting of iron base metal powder and solid lubricant having covered layer covered with metal or ceramic is compacted to a green compact. Successively, the green compact is sintered to sintered compact having pores in the inside. By this method, adhesion strength with matrix is improved, even in heating to 1000-1200°C at sintering process and 800-850°C at impregnating aluminum base metal, decomposition of solid lubricant is prevented due to existence of covered layer.
