A sliding material exhibiting excellent initial compatibility, excellent sliding characteristics even under severe sliding conditions, especially excellent frictional characteristics and wear resistance under fluid lubrication, boundary lubrication and dry lubrication, and having a solid state lubrication coating film. The sliding material having a solid state lubrication coating film on a planar basic material is characterized in that a plurality of concentric grooves are made in the circumferential direction on the sliding surface and a ridge is formed between adjacent grooves.
