To provide a resin molded article capable of enhancing visibility of engraved contents without providing a specific area along contours of letters and the like to be engraved, and a method for manufacturing the molded article.SOLUTION: A first surface 21 of a resin molded article 1 is provided with a recess 22 that forms a contour of a letter, a symbol, a figure, and the like indicated by an indication mark. Inside of the recess 22 is provided with a plurality of protrusions 23. A protrusion height A1 is shorter than a recess depth B1. A surface roughness of the first surface 21 is larger than a surface roughness of a second surface 22A including a bottom 221 and the protrusion 23 of the recess 22.SELECTED DRAWING: Figure 4
【課題】刻印する文字等の輪郭に沿って特定の領域を設けることなく、刻印内容の視認性を向上できる樹脂成型品及び樹脂成型品の製造方法を提供する。【解決手段】樹脂成型品1の第一表面21には、表示マークが表示する文字、記号、図形等の輪郭を形成する凹部22が設けられる。凹部22の内側には、複数の凸部23が設けられる。凸部高さA1は、凹部深さB1よりも短い。第一表面21の表面粗さは、凹部22の底部221及び凸部23を含む第二表面22Aの表面粗さよりも大きい。【選択図】図4
