PROBLEM TO BE SOLVED: To provide a polyacetal resin composition developing little lowering of mechanical properties, especially creep property after leaving for a long period in a molten state. SOLUTION: The polyacetal resin composition contains (A) 100 pts. wt. of a polyacetal resin composed of 0-99.999 wt.% linear polyacetal and 100-0.001 wt.% branched or reticulated polyacetal and (B) 0.001-10 pts. wt. of a metal salt of a carboxylic acid expressed by general formula (I) (R<SP>1</SP>and R<SP>2</SP>are the same or different and each independently a group selected from hydrogen atom and≤10C organic groups; m and n are each an integer of 0-5 provided that m+n is an integer of 0-5; and X is a group selected from hydroxy group, formyl group, amino group, ester group and alkoxy group).
