PROBLEM TO BE SOLVED: To provide a polyoxymethylene resin composition having excellent heat stability capable of withstanding high temperature and long-term molding. SOLUTION: The polyoxymethylene resin composition is obtained by adding (A) a hindered amine compound having a molecular weight of≥400, (B) a hindered phenolic compound having a molecular weight of≥400, and (C) a phosphate of an alkali metal or an alkaline earth metal to a polyoxymethylene. Further, the amount of a formic ester terminal group is≤0.03 mol%. COPYRIGHT: (C)2004,JPO
