ABSTRACT The present invention provides a polyoxymethylene composition which is improved in heat stability, so that little mold deposit is formed even after long-term continuous molding and the generation of formaldehydric odor is remarkably inhibited in processing and molding, and which is characterized by containing 0.01 to 5% by weight of a hindered phenol antioxidant, 0.01 to 10% by weight of a melamine- formaldehyde polycondensate and 0.05 to 4% by weight of a fatty acid ester of a polyhydric alcohol, each amount being based on the whole composition.
