Polyoxymethylene is blended with 0.01 to 5.0 wt. %, based on the polyoxymethylene, of an antioxidizing agent and 0.0005 to 0.5 wt. %, based on the polyoxymethylene, of magnesium oxide and/or calcium oxide to give a polyoxymethylene composition improved in malfunctions due to formic acid generated from the composition (e.g., contamination with bloom from rubber and corrosion of a metallic magnetic material).
