Abstract

The invention is a polyacetal resin composition containing a polyacetal resin (A) and a polyethylene resin (B), in which the blending proportion of the polyacetal resin (A) occupying in the total mass of the polyacetal resin (A) and the polyethylene resin (B) is 10 to 90 mass %, the melt flow rate of the polyacetal resin (A) measured at a condition of 190° C. and 2.16 kg load is 30 g/10 minutes or less, and the polyethylene resin (B) consists of a modified polyethylene resin and the modification rate is 0.01 mass % or more based on 100 mass % of the total mass of the polyethylene resin and the melt flow rate of the polyethylene resin (B) measured at a condition of 190° C. and 2.16 kg load is 2.5 g/10 minutes or less.
