PROBLEM TO BE SOLVED: To provide a polyoxymethylene resin composition having high thermal stability, good moldability and excellent in appearance with little foreign matters. SOLUTION: The polyoxymethylene resin composition contains 100 pts.wt. of a polyoxymethylene resin and 0.01-10 pts.wt. of an alkoxymethylguanamine represented by general formula (I) [wherein R is H, a 1-22C hydrocarbon group, a halo- or nitro-substituted hydrocarbon group, an aryl group, an aralkyl group, or a 3-10C cycloalkyl group; and R1 to R4 are each H or an alkoxymethyl group -CH2 OR' (wherein R' is a 1-8C alkyl group), provided that at least two of R1 to R4 comprise each an alkoxymethyl group].
