Disclosed is a polyacetal resin composition which is composed of a polyacetal resin and a hydrazide of a heteroatom-containing aliphatic carboxylic acid. The hydrazide of a heteroatom-containing aliphatic carboxylic acid may be contained in an amount of 0.001-20 parts by weight per 100 parts by weight of the polyacetal resin. The polyacetal resin composition may further contain at least one substance selected from antioxidants, heat resistance stabilizers, processing stabilizers, weathering (light resistance) stabilizers, impact strength modifiers, gloss control agents, sliding property modifiers, coloring agents and fillers. With such a resin composition, stability of the polyacetal resin is improved, while suppressing generation of formaldehyde.
