PROBLEM TO BE SOLVED: To obtain a polyoxymethylene resin composition extremely high in thermal stability, good in moldability, less in foreign matter generation, and excellent in external appearance. SOLUTION: The polyoxymethylene resin composition is prepared by compounding (B) 0.01-10 pts.wt. of a heat stabilizer having a triazine structure containing an amino group to (A) 100 pts.wt. of a polyoxymethylene resin. The heat stabilizer is a reaction product of formaldehyde containing 2.0 wt.% or less of free formaldehyde content with a triazine compound containing an amino group and/or a derivative wherein the methylol groups bonded to the amino groups in the reaction product are partially or wholly alkylated.
