Provided is a polyacetal resin composition suitable for providing a plate-shaped resin molded article that satisfies all of the following: high flatness, low shrinkage ratio anisotropy (high dimensional stability), high creep resistance, high impact strength, and excellent color stability during residence in the molding machine. The polyacetal resin composition for molding a plate-shaped molded article according to the present invention comprises: (A) 100 mass parts of a polyacetal resin having a melt index (according to ASTM D1238, 190°C, 2.16 kgf) of 2.0 g/10 min to 4.0 g/10 min; (B) 0.1 mass parts to 2 mass parts of a polyacetal copolymer that is a copolymer of (b1) trioxane, (b2) a compound having two to four cyclic ether units per one molecule, and (b3) a compound having one cyclic ether unit per one molecule, the polyacetal copolymer having a branched or crosslinked structure; and (C) 0.1 mass parts to 1 mass part of a hindered phenol antioxidant.
