To provide a polyacetal resin composition and a molded article thereof, which are less likely to crack even if stressed in contact with any hydrochloric acid-containing liquid. The polyacetal resin composition contains, per 100 parts by mass of a polyacetal resin: 0.01 to 10 parts by mass of at least one fatty acid metal salt selected from 1) to 3) below; and 0.1 to 5 parts by mass of a stress relaxant having a melting point of 67.5° C. to 200° C. when measured by using a differential scanning calorimeter at a flow rate of nitrogen of 20 cm3/min and at a heating rate of 10° C./min.1) metal salt formed of long chain fatty acid having 10 to 34 carbon atoms and calcium;2) metal salt formed of long chain fatty acid having 10 to 34 carbon atoms and zinc; and,3) metal salt formed of long chain fatty acid having 10 to 34 carbon atoms and magnesium.
