PROBLEM TO BE SOLVED: To provide a polyacetal resin material which maintains and improves the excellent original characteristics, such as mechanical characteristics, processability and surface characteristics, of a polyacetal resin and ultimately reduces the production of a gas, such as formaldehyde. SOLUTION: This polyacetal resin composition comprises 100 pts.wt. of a polyacetal resin (A1) substantially having a straight chain molecular structure, 0.01 to 20.0 pts.wt. of a polyacetal resin (A2) having a branched or cross-linked structure, 0.01 to 5.0 pts.wt. of a hindered phenolic anti-oxidation agent (B), and 0.01 to 5.0 pts.wt. of a hydrazide compound (C).
