PROBLEM TO BE SOLVED: To provide a resin molding which has high durability, simultaneously satisfies excellent slidability from an initial period and has high strength, and has high productivity and high quality.SOLUTION: A polyacetal resin molding contains: (A) a polyacetal resin; (B) 10 pts.mass or more and 100 pts.mass or less of a glass-based filler with respect to 100 pts.mass of (A) the polyacetal resin; and 0.5 pts.mass or more and 8 pts.mass or less of (C) a polyethylene resin having a weight average molecular weight of 500,000 or less, where the abundance of the (C) polyethylene resin having the weight average molecular weight of 500,000 or less within 10 nm from the surface layer of the molding is more than the abundance of the (C) polyethylene resin having the weight average molecular weight of 500,000 or less within 10 nm from the surface layer in a surface in which a layer deeper than the surface layer of the molding by 1,000 μm is cut out.SELECTED DRAWING: None |
