PROBLEM TO BE SOLVED: To provide a polyacetal resin composition that can suppress generation of formaldehyde and contamination of a mold at fabrication.SOLUTION: A polyacetal resin composition includes 0.05-5 parts by mass of a hydrazide compound shown by the following formula based on 100 parts by mass of a polyacetal resin. (R-NH-NH-CO-)-R-(-CO-NH-NH-H). In the formula, m denotes a positive integer; n denotes 0 or 1; Ris a (m+n)-valent group, and denotes a 1-40C aliphatic hydrocarbon group, a 3-40C alicyclic hydrocarbon group, a 6-10C aromatic hydrocarbon group, a 2-5C heterocyclic group or a main chain of a polymer, and may be a single bond when m=1, n=1, and Rmay be a hydrogen atom when m=1, n=0; Ris a univalent group and denotes a 1-40C aliphatic hydrocarbon group, a 3-40C alicyclic hydrocarbon group, a 6-10C aromatic hydrocarbon group or a 2-5C heterocyclic group. |
