To provide a highly rigid and tough polyacetal resin composition and a resin slide member produced by molding the polyacetal resin composition, which has less limitation of a sliding counterpart material and can cope with a friction/abrasion condition over a wide range, by improving frictional/abrasion characteristics of a conventional polyacetal resin composition.

The polyacetal resin composition is prepared by blending a polymer having an aliphatic ester structure, a polyethylene wax, and silicone oil with a polyacetal resin. The resin slide member is produced by molding the polyacetal resin composition.
