PROBLEM TO BE SOLVED: To provide a polyacetal resin composition excellent in weatherability and heat stability, suppressing amount of formaldehyde generation and reduced in mold contamination. SOLUTION: The polyacetal resin composition comprises 100 pts.wt. (A) polyacetal resin, 0.01-5 pts.wt. hindered amine-based optical stabilizer expressed by general formula (1), 0.01-5 pts.wt. (C) UV absorber and 0.01-5 pts.wt. (D) hydrazide compound. (In the formula, X expresses an organic group bonding with N through C at the bonded position; Y expresses H or an organic group bonding to 4-position of the piperidyl group through O or N).
