摘要：
A plastic molded article has an external appearance of a coated article and is formed by injection molding using a mold with a surface shaped by forming machining marks in the form of recesses over the entire mold surface. The resulting plastic molded article has a center line average roughness of the surface shaped of the plastic molded article less than 0.5 .mu.m and one of either an average slope within the range of 1.0.about.10.0.degree. or an average peak-to-peak interval within the range of 5.0-30.0 .mu.m.
