摘要： Disclosed is a polyoxymethylene resin composition that includes a filler in an amount of about 5 to 30 wt %, a formaldehyde reducing agent in an amount of about 0.01 to 1 wt %, and a polyoxymethylene resin constituting the remaining balance of the polyoxymethylene resin composition, all the wt % based on the total weight of the polyoxymethylene resin composition. In particular, per 1 g of the polyoxymethylene resin may include an amount of 30 to 40 μmol of formate at terminal ends of the polyoxymethylene resin.
